Katy Perry is an American pop singer and songwriter.

Real name Katheryn Elizabeth Hudson, [[StageName Katy Perry]] was born as the second child to Christian pastor parents Keith Hudson and Mary Hudson (neé Perry) on October 24, 1984 in [[UsefulNotes/{{California}} Santa Barbara]]. Along with her older sister and younger brother, she was raised in a deeply religious family.

Growing up listening to only gospel music, her first experience of performing was singing in church, thus a passion for music grew. At the age of fifteen Perry began visiting Nashville, gaining experience of recording demos and songwriting. At some point, Katy signed on to Christian record label Red Hill, and at the age of 17, she released a Christian pop album under her birth name but wasn't successful.

Perry then moved to UsefulNotes/LosAngeles, collaborating with producer Glen Ballard though was unable to secure a lasting record deal. She signed to Creator/ColumbiaRecords in 2004, but was dropped when this proved futile. However, an executive at Columbia recommended Katy Perry to Jason Flom, Virgin Records’ chairmen, resulting in her singing for Capitol Music Group.

She recorded her first album ''One of the Boys '' and in spring of 2008, released lead single ''I Kissed a Girl'', which proved to be a smash hit at number one slot in several countries where other hit singles followed, the album becoming a commercial success. Her second album, ''Teenage Dream'' spawned more huge hits where many awards and music industry records followed. In 2012, she released the documentary feature film ''Katy Perry: Part of Me'', and ''Teenage Dream'' was re-released to promote the film.

In 2013, she struck back with the fierce "Roar" and announced that her third album, ''Prism'', was going to be released in October 2013.

She married English comedian RussellBrand in 2010, but they divorced in early 2012 and owns a cat named Kitty Purry who has its own blog. Yes, [[http://katyperryblog.tumblr.com/page/2 really]]. [[CelebrityResemblance As noted by certain people, she looks like]] Creator/BettiePage and Creator/ZooeyDeschanel. [[http://www.youtube.com/watch?v=qovkNQDUcq8 Katy herself]] declared she'd like to make a movie where she and Zooey played CreepyTwins.

----
!![[MemeticMutation I used these tropes and I liked them; the taste of their cherry Chap-Stick]]!

* AccidentalPun: A line from "I'm Still Breathing":
-->Already lost our grip, best {{Abandon Ship|ping}}, oh
** The song could be about an insecure girl who's either attempting suicide or "killing off" her relationship and doesn't hope for the guy to remember her for fear of guilt.
* AcCENTUponTheWrongSylLABle: "[=UnCONdiTIONally=]".
* {{Adorkable}}: "Last Friday Night."
** Also, her in the behind the scenes of "Last Friday Night". (Along with almost every other star in it.)
* AesopAmnesia: In-universe, in "Last Friday Night".
-->Yeah I think we broke the law/Always say we're gonna stop-op/Whoa-oh-oah/This Friday night/Do it all again.
* AllJustADream: Played with in "Roar". At the end of the video Katy wakes up back in her airplane seat, [[spoiler: but it turns out she's turned the wrecked plane into her shelter on the island.]]
* AmazonBrigade: In "Part of Me".
* AmbiguousGender: The LittlestCancerPatient in the music video for "Firework."
* AncientEgypt: The setting for the "Dark Horse" music video, featuring Katy as a Cleopatra-like pharaoh.
* AndThatLittleGirlWasMe: The twist endings in "Pearl" and the "Wide Awake" music video
* ArtisticLicenseAstronomy: Unless she is singing about WesternAnimation/SpaceGhost in "E.T.," the words "extraterrestrial" and "supernatural" don't really have anything to do with each other.
* AscendedExtra: The Kathy Beth Terry character first appeared at the 2010 Teen Choice Awards, which Katy hosted.
* AutoErotica: Mentioned in "The One that Got Away":
-->Summer after high school when we first met/We make out in your Mustang to Music/{{Radiohead}}...
* BaitAndSwitchLesbians: Katy Perry had a sizable lesbian fan base after the release of "I Kissed a Girl" [[IsntItIronic until they actually listened to the lyrics]] and realized that the song was about a heterosexual girl's drunken experiments. And, for the more usual use of the trope... in the music video, she ''never does''.
* BigBreastPride: She is '''very''' proud of them and the {{Fanservice}} in her videos and concerts is deliberate and intentional.
--> "I lay on my back one night and looked down at my feet, and I prayed to God. I said, 'God, will you please let me have boobs so big that I can't see my feet when I'm lying down?'"
* BillingDisplacement: In the Last Friday Night video DarrenCriss has a ten-second cameo and gets a starring credit, Richie Nuzzolese who plays one of the main love interests is listed as an extra.
* BlackBestFriend: Music/{{Rihanna}}
* BoldlyComing: "E.T."
* BracesOfOrthodonticOverkill: Katy wears them as Kathy Beth Terry in the music video for "Last Friday Night".
* BreakupSong: "Part of Me", "Ghost", "Not Like The Movies".
* TheCameo: [[http://www.youtube.com/watch?v=KlyXNRrsk4A The video for Last Friday Night]] has tons: DarrenCriss, KevinMcHale, Music/KennyG, Music/{{Hanson}}, Music/RebeccaBlack, Corey Feldman, and Debbie Gibson.
** Her movie features Music/LadyGaga, Music/JustinBieber, Music/RebeccaBlack, Music/{{Adele}}, [=Rihanna=] and Music/JessieJ.
* CanonDiscontinuity, {{Retool}}: How many people actually knew of Katy's first album? It seems to have slipped under the radar of even Christian pop fans.
* CaptainErsatz: See the GermansLoveDavidHasselhoff section.
* [[ChristianRock Christian Pop]]: Her first album.
** Some songs from ''Prism'' could fall into this, such as "By the Grace of God" and "Spiritual".
* CleavageWindow: [[http://www.contactmusic.com/in-pictures/katy-perry-ignores-grammys-dress-code-in-flesh-baring-dress-pictures_3496636 At the Grammys]]
* TheCobblersChildrenHaveNoShoes: She's the [[PreachersKid daughter of pastors]], so naturally, she sings songs about [[HoYay lesbian experimentation]], has music videos of her smiling seductively while wearing nothing but cotton candy over her ass, and does dance moves that mimic blow jobs.
** Averted at first, since she started off as a Christian "Rock" singer. Also, she still considers herself to be a Christian, and even has a "Jesus" tattoo on her left wrist.
* ContinuityNod: Her music video for "Wide Awake" starts off at the end to "California Gurls". After the music video ends, she goes onstage at a concert to perform "Teenage Dream". Other less obvious ones includes : the strawberry about One Of The Boys (the album)/the Hello Katy Tour and various nods at the videos for Last Friday Night, Part Of Me, E.T and most obviously Firework.
** The video for "This Is How We Do" features a scene where Katy has a Watermelon (Hot N Cold CD single), Heart shaped glasses (Teenage Dream era) and a Pizza dress (referencing the pizza, ItMakesSenseInContext, from the Prismatic World Tour).
* CostumePorn: Her California Dreams tour was a showcase for an array of crazy/cartoonish/candy-themed costumes.
** The video for "Unconditionally" is a more traditional example of this, being inspired by Anna Karenina.
* DarkerAndEdgier: "Circle the Drain" sounds ''much'' darker than her typical upbeat pop music. Also, "E.T" could fall under this.
** Perry herself said that ''Prism'' would be this. The album later had a more happier direction, but still, most of the second half of the album (such as "Ghost", "Spiritual" and "By the Grace of God") sound ''very'' darker (and at times even sadder) than your average Katy Perry song.
* {{Dedication}}: International Smile for Mia Moretti, her muse.
* DoesNotLikeMen: Some people accused her of being a misandrist after her first album, which contains such pleasantries as "Yeah you... PMS... like a bitch... I would know!" being said to a guy ("Hot 'n' Cold"), a song about how gay a guy is ("Ur So Gay", obviously; emasculating him for being a [[RealMenEatMeat vegetarian]], [[ArsonMurderAndJaywalking even]]), and an Franchise/ArchieComics-esque song about how a guy must always foot the bill ("If You Can Afford Me"). Katy appears to have [[AvertedTrope averted this trope]], though.
* DoNotTauntCthulhu: "Dark Horse"
* DrivenToSuicide: By The Grace Of God she stopped being so depressed.
* EarlyBirdCameo: Kathy Beth Terry, her nerdy alter-ego from "Last Friday Night", first appeared at the 2010 Teen Choice Awards.
** Prior to "I Kissed A Girl" breaking her into the mainstream, Katy herself is seen as the LastGirlWins in the music video for Gym Class Heroes' "Cupid's Chokehold".
* EarlyInstallmentWeirdness: That Christian pop album.
* EpicFail: She mentions this trope by name in "Last Friday Night".
* FlippingTheBird: In the "California Gurls" music video, a gummi bear gives Katy the finger (though it's censored).
* ForbiddenFruit: In "I Kissed a Girl"
--> It felt so wrong. It felt so right."
* FormerFriendOfAlphaBitch: Music/RebeccaBlack in the Last Friday Night series of promotional videos. She and Kathy Beth Terry reconcile in the actual music video.
* FriendToAllLivingThings: She becomes one after she ends up in a jungle in the music video for "Roar"; an elephant gives her a shower with its trunk, she brushes the teeth of a crocodile and tames a tiger and makes it her pet.
* FunnyBackgroundEvent: Many of her videos feature some. "California Gurls" has a sign edited to say Sundae Boulevard instead of Sunset.
* GagBoobs: Where to start? In her various videos, her breasts have shot out fireworks, whipped cream and glitter. She's worn bras made out of candy, dice, pokeballs and practically everything imaginable. They're practically comedy props by now.
** And, don't forget her guest shot on SNL, when the Elmo T-shirt she wore had some Really Big Eyes.
* GenkiGirl: When appearing on talk shows, she's extremely cheerful and excitable.
* GettingCrapPastTheRadar: "Peacock".
** "Last Friday Night (T.G.I.F.)" go completely uncensored on the radio.
* GirlinessUpgrade: The focus of "One of the Boys" (the song), which is about a {{Tomboy}} becoming a GirlyGirl as she enters puberty, no longer wanting to be "OneOfTheBoys."
* GirlOnGirlIsHot: There's a reason that "I Kissed a Girl" was number one for 8 weeks.
* HollywoodNerd: She plays a Type 2 in the video for "Last Friday Night".
* HollywoodOld: In "The One That Got Away" video.
* HotWitch: WordOfGod is that "Dark Horse" is inspired by the idea of a witch warning a man [[http://www.mtv.com/news/articles/1713269/katy-perry-dark-horse-prism.jhtml not to fall for her]]. Naturally, her performance of it for the 2014 Grammys [[http://www.youtube.com/watch?v=ZSaxGesjybA went with this]] to the point of having poledances on broomsticks.
* HypocriticalHumor: The first song she released, "Ur So Gay", emasculates a man for acting stereotypically gay. She followed it up with "I Kissed A Girl", a song about lesbian experimentation.
* IdenticalStranger: Zooey Deschanel.
* IgnorantOfTheirOwnIgnorance: People who failed to realize that [[http://www.youtube.com/watch?v=wbqFMgdSeGs this supposed fail]] was a scripted joke she made [[http://www.youtube.com/watch?v=sM51ANnSgsU at multiple shows]].
** Also in "Wide Awake": "I wish I knew then, what I know now."
* TheIlluminati: {{Discussed|Trope}}. Dear sweet goodness, there were so many accusations of her affiliation with the illuminati after her video for "Dark Horse" and it got [[FromBadToWorse even worse]] with her live performance at the grammys.
* ImportantHaircut: In the [[http://www.youtube.com/watch?v=uuwfgXD8qV8&feature=channel Part of Me video]], after she breaks up with her cheating boyfriend, she cuts her hair short and joins the Marines.
* IntercourseWithYou: "Dressin' Up", "Teenage Dream", "Birthday", "Legendary Lovers", "Hummingbird Heartbeat", "E.T.", "Last Friday Night (T.G.I.F.)" (though not all about it).
* {{Irony}}: Both parents were highly conservative pastors that didn't allow their children to watch ''WesternAnimation/TheSmurfs'' [[Creator/HannaBarbera cartoon show]], considering it to not be good for Katy and her siblings. Guess which blonde Smurf she voices in the 2011 ''Film/TheSmurfs'' and its [[Film/TheSmurfs2 two]] [[Film/TheSmurfs3 sequels]]?
* JunglePrincess: She becomes one in the music video for "Roar".
* KaleidoscopeHair: Katy is constantly changing her hair color. It's gone from blond to black to [[FieryRedhead red]] to blond to pink to blue to purple, back to black and now green after a brief orange and black phase. That's not counting purple, pink, blue and now [[http://wonderwall.msn.com/music/gossip-orange-crush-katy-perry-poses-with-flaming-locks-21489.gallery orange]] wigs.
* KindheartedCatLover: She loves cats as she named her own cat [[PunnyName Kitty Purry]] her mascot, and joked that she wants to make the CrazyCatLady persona cool. At the end of the lyric video for "Roar", she holds up Kitty, coos at her, then kisses her on the head.
* LevelAte: The "California Gurls" video.
* LoudnessWar: Her albums have an average dynamic range of 5 db. That's louder than ''Music/{{Megadeth}}''.
* LyricSwap: When performing Part Of Me, she sings "You let me drown" instead of "you let me down".
** Also the line "We drove to Cali" in Teenage Dream changes according to where she performs.
* LyricVideoMismatch: For "California Gurls" and "Dark Horse".
* MakeoverMontage: In "Last Friday Night".
* MaleGaze: Her Victoria's Secret performance featured a LOT of cleavage shots.
** The bra she wears in the climax of the "Roar" video can be considered this.
* MeaningfulEcho: "Wide Awake" refers to a lot of "Teenage Dream"'s lines in a depressing way but not verbatim. "You make me feel like I'm living a teenage dream" vs "Everything you see/Ain't always what it seems/I'm wide awake/yeah I was dreaming for so long" and "My missing puzzle piece/I'm complete" vs "I picked up every piece", "need nothing to complete myself".
* MissingTrailerScene: The [[http://www.youtube.com/watch?v=Ghe52kEPpAQ&feature=related "Last Friday Night" video teaser]] is almost entirely made of scenes that didn't make the final video cut.
* {{Mondegreen}}: The official lyrics in "Firework" is ''gonna leave them all in awe'', instead of ''gonna leave them falling down'', which was stated in lyric websites.
* MoodWhiplash: On the Teenage Dream album, "Firework" is immediately followed by "[[RefugeInAudacity Peacock]]", which itself is followed by "Circle the Drain".
** On ''Prism'', "International Smile" is followed by "[[TearJerker Ghost]]".
* TheMovie: ''[[http://www.youtube.com/watch?v=K16NvLCk2CY Katy Perry: Part of Me]]''
* MsFanservice:
** Invoked in "Teenage Dream":
--->"I set your heart racing in my skintight jeans"
** Blatantly embraced. She's done videos completely naked except for strategically placed cotton candy, running around a jungle in a skimpy leapord skin bra with a grass skirt, had her boobs shoot whip cream and fireworks... she is MsFanservice full stop.
* NerdsAreSexy: In the video for "Last Friday Night," she plays a Type 2 HollywoodNerd who [[SheCleansUpNicely gets a makeover]]. However even post-makeover, she retains her braces and her nerdy mannerisms, resulting in this trope.
* NonAppearingTitle: Although they come close, "Hot n Cold" and "E.T.".
* NoPeriodsPeriod: Not quite to the AllPeriodsArePMS exception levels, but "Hot N Cold". %%TODO: fix trope
-->You PMS like a bitch, I would know.
* OddFriendship: Is surprisingly really good friends with [=Adele=] and Music/TaylorSwift. She's actually friends with a lot of people in the business including Music/SelenaGomez, [=Jessie J=], Justin Bieber, RobertPattinson.
* OneOfTheBoys: The name of her debut (pop) album and its title track. The song is about a [=tomboy=] [[GirlinessUpgrade becoming a]] [[TomboyAndGirlyGirl girly girl]] as she enters puberty and no longer wants to be "one of the boys".
* TheOneThatGotAway: Has a song by this name about this in which she laments about a former lover. This is her only song from Teenage Dream not to go to #1, making it [[IncrediblyLamePun the #1 that got away]].
* ParallelPornTitles: [[http://www.imdb.com/title/tt2073008/ Yes, really]].
* PeacockGirl:
** A showgirl outfit she wears in "Waking Up In Vegas".
** And a peacock tail for "Peacock".
* PreachersKid: Katy's parents are pastors at a church in Santa Barbara, and they refused to let her listen to "secular" music as she was growing up. This [[FreudianExcuse may explain]] her more recent output.
* PrecociousCrush: "One of the Boys"
* ProductPlacement: {{Subverted|Trope}}. She mentions Chap-Stick in "I Kissed a Girl" and Popsicles in "California Girls", but those trademarks are [[BrandNameTakeover incredibly diluted]].
** Played straight in "Last Friday Night". She and some other people are seen playing JustDance on a Wii.
* PunBasedTitle: ''Teenage Dream: The Complete Confection'', which a play on words of "Complete Collection". [[JustifiedTitle It makes sense in context]], taking the candy motif of the album into consideration.
* PunnyName: She named her cat - and, in the "Roar" music video, a tiger - Kitty Purry.
* PrinceCharming: Katy meets such a character at the end of the "Wide Awake" music video... and punches him in the face.
* [[RealLifeWritesThePlot Real Life Chose The Single]]: "Part of Me" was originally written back in 2010 during the ''Teenage Dream'' sessions, but left off the album for unknown reasons. Upon Katy's divorce from Russell Brand in 2012, the song was repurposed as the lead single of ''Teenage Dream'''s [[UpdatedReRelease re-release]], with slightly altered lyrics to reflect their separation.
* RearrangeTheSong: "The One That Got Away" was released both as synth-pop and as an acoustic song featuring guitar, piano, and upright bass.
* TheReasonYouSuckSpeech:
** "Circle the Drain" is this towards [[GymClassHeroes Travie [=McCoy=]]].
** "Hot and Cold" gives one of these to the narrator's boyfriend.
* RefugeInAudacity: "Peacock", [[http://www.youtube.com/watch?v=ppUm3TFnhtk full stop]].
** "Birthday", which uses a LOT of party-related metaphors to obscure it's an IntercourseWithYou song. It goes from subtle, to being very unsubtle ("Pop your confetti, Pop your Pérignon / So hot and heavy till dawn"), to being downright {{Anvilicious}} ("So let me get you in your birthday suit / It's time to bring out the big balloons").
* RockStarSong: "Wide Awake" is this in the sense it's about after all the positive press goes away "Falling from cloud nine/In front of the world".
* [[{{Rockumentary}} Pop-cumentary]]: ''Part of Me''
* {{Scotireland}}: Once told [[http://www.youtube.com/watch?v=JGhDp8wYH-A&feature=player_embedded#at=188 an interviewer]] she was hoping to see the Loch Ness Monster while in Ireland.
* SemperFi: In the music video for "Part of Me", after Katy breaks up with her cheating boyfriend, she joins the Marines and regains her confidence.
* SesameStreetCred: She was quite proud of [[http://www.youtube.com/watch?v=YHROHJlU_Ng this appearance with Elmo]]. ''Series/SesameStreet'' producers, however, decided not to air the segment after some parents [[TooSexyForThisTimeSlot complained about her cleavage]]. This was, of course, brought up on ''SaturdayNightLive'', where Perry appeared in a talk show sketch as a teenage volunteer librarian wearing a low-cut [[TakeThat Elmo T-shirt]] and complaining that the parents and the other librarians don't want her to read to kids because of her cleavage-bearing clothes (with the two talk show hosts [played by Creator/AmyPoehler and Maya Rudolph] telling her that she shouldn't be ashamed about her body and that there are worse things kids witness in their formative years than a woman's cleavage). Her appearance on the ''[[WesternAnimation/TheSimpsons Simpsons]]'' episode, "The Fight Before Christmas" also mirrors this unaired Sesame Street sketch (only Katy's dress was more skintight than cleavage-bearing, though it did get away with a oral sex joke at the end with Moe kissing Perry's "belly button").
* SerialEscalation: She broke her own record for the song with the most spins on Pop radio three times and keeps on extending her make for the most consecutive Dance #1 hits (currently: 13).
* SheCleansUpNicely: In "Last Friday Night," complete with her descending the stairs in slo-mo and garnering a gobsmacked expression from the JerkJock.
* ShoutOut: In her earlier photoshoots, she looked like Bettie Page.
** In "California Gurls", Snoop Dogg mentions that he "[[Music/TheBeachBoys wishes they could all be California girls]]", Also, from the same song: "[[Series/TheDukesOfHazzard Daisy Dukes]], bikinis on top!", "sippin' gin 'n' juice", and "[[Creator/VinceOffer zucchinis, martinis, bikinis]]". And from the music video of the same song, a couple of ''Franchise/PrettyCure'' fans noticed that when she wore the light purple wig, she looked like a short-haired [[Anime/FreshPrettyCure Cure Berry]].
*** That particular Beach Boys shout-out was taken as so specific that the fans thought the Beach Boys would sue. However, the surviving members had no intention, and took it as a compliment.
** The title of the song was originally spelled "California Girls", but Katy's manager asked her to change it to "Gurls" as a reference to Music/BigStar's "September Gurls" after Alex Chilton died — apparently, he's a huge Music/BigStar fan.
** If one listens closely to the music in the background of "E.T."'s chorus, the sound of an [[ModernWarfare AC-130's 105mm cannon]] can be discerned.
** Wide Awake takes liberal visuals from ''Literature/AliceInWonderland'', ''Literature/ThroughTheLookingGlass'' and the ''Literature/{{Narnia}}'' books. It's also deliberately inspired by ''TheCraft''.
** The visuals on her first album cover are inspired by ''Literature/{{Lolita}}''.
** The video for "Unconditionally" takes inspiration from ''Literature/AnnaKarenina,'' right down to the ending.
** The video for "This Is How We Do" features ones to Mariah Crey and Aretha Franklin, the song itself is full of shout-outs.
* SpiritualSuccessor: To Britney Spears, positive pop with hidden depths. Their personalities are DEFINITELY alike if you watch ''Part of Me'' next to ''For the Record''.
* StageName: She was born as Katheryn Elizabeth Hudson. Perry is her mother's maiden name.
* StrongFamilyResemblance: Katy's older sister [[http://www.youtube.com/watch?v=K3Cw488fK-A Angela Hudson]] looks and sounds exactly like her except she has blonde hair[[note]]so does Katy but she dyes it[[/note]] and a more introverted personality.
* SurrealMusicVideo: "California Gurls", "E.T" (a few people think she [[UpToEleven out-Gaga'd Lady Gaga]] in that one), "Wide Awake", and "Dark Horse".
* TheVJDayKiss: She reenacted the kiss [[http://www.dailymail.co.uk/femail/article-2151687/Is-new-Kiss-photo-Black-white-snap-Katy-Perry-locking-lips-marine-mirrors-iconic-WWII-moment.html with a Marine]] when she was giving a show during the New York Fleet Week as well as during [[http://www.youtube.com/watch?v=BplrgIa2yPg a private show for the Navy]].
* ThreeWaySex: "Last Friday Night" mentions having a menage a trois.
* TomboyAndGirlyGirl: "One of the Boys" is about a [=tomboy=] becoming a girly girl as she enters puberty.
* TookALevelInBadass: In the music video for "Roar", Katy goes from being a scared out of her wits woman to the queen of the jungle, even managing to tame a tiger and keeping it as a pet.
* TooSexyForThisTimeSlot: The entire outcry over [[SesameStreetCred her appearance]] on ''Sesame Street''.
* TorpedoTits:
** In the "Firework" video.
** "California Gurls", except with whipped cream.
* {{Tsundere}} The premise of ''Hot-N-Cold.''
* TwoDecadesBehind: Parodied and deconstructed in "Last Friday Night".
* UnderwaterKiss: In the music video for "Teenage Dream".
* UnusualEuphemism: In every other song. She's quite creative.
* VineSwing: As a JunglePrincess, in her music video for "Roar".
* [[WearingAFlagOnYourHead Wearing a Flag on your Dress]]: See the page picture.
** And [[http://images.safm.com.au/2012/05/25/764687/katy-perry-fleet-week-395.jpg this one]] which she wore when she performed for the troops on New York's Fleet Week.
* WeNamedTheMonkeyJack:
** Type 1. She named her cat "Kitty Purry". In the music video for "Roar", she tames a tiger and gives it the same name.
** And one named Krusty (Katy+Russell/Rusty), with her ex-husband Russell Brand.
* WhatDidIDoLastNight: The subject of "Last Friday Night" and "Waking Up in Vegas".
* WildTeenParty: Occurs in the video for "Last Friday Night".
* AWildRapperAppears: A few of her songs on 'Teenage Dream'. "California Gurls" featured Music/SnoopDogg, "E.T." featured Music/KanyeWest, whilst the radio versions of "Last Friday Night" and "The One That Got Away" featured Missy Elliott and B.o.B respectively.
** A remix of "Teenage Dream" exists featuring Music/{{Drake}}.
** From ''Prism'' we can add "Dark Horse," featuring former ThreeSixMafia member Juicy J. Actually rather fitting though given the whole song uses a [[TrapMusic trap-rap]] beat. There is also a version featuring {{Pitbull}}.
* XtremeKoolLetterz: "Hot N Cold", "Ur So Gay", "California Gurls"
* YouAreNotAlone: The intended message of "Firework".
