! Trope trope into the room, I know you want them:

* AdultsAreUseless: All three adults in the "Who's Laughing Now" video are aloof to Young Jessie's actions.
* AliceAllusion: The tea party table in "Nobody's Perfect".
* AnalogyBackfire: "Masterpiece" is supposed to be a positive song about accepting your flaws, but a few lines have the effect of discrediting her previous work as "not that great", specifically, "You haven't seen the best of me/I'm still working on my masterpiece".
* ApatheticTeacher: The teacher in "Who's Laughing Now" is shown at her desk rolling her eyes and showing lack of interest at the chaos in her classroom.
* AudienceParticipationSong: In live versions of "Wild", Jessie J has the audience sing back the "wild, wild, wild, oh-woah-oh" part.
* AWildRapperAppears:
** B.o.B. spontaneously appears in "Price Tag".
** Taken to another level in "Wild". On the British single, both Music/BigSean and Dizzee Rascal do verses, with only a chorus separating them. In the American single, only Big Sean gets to rap.
** 2 Chainz in "Burnin' Up".
* BeYourself: ''Don't lose who you are / in the blur of the stars ...''
* CloudCuckooLander: She plays up this aspect of her personality in interviews.
* CoveredInGunge: In the video for "Who's Laughing Now", Young Jessie sprays her entire class of bullies with fire extinguisher fluid.
* CreatorInJoke: "Price Tag" starts with an ad-lib referring to "Coconut Man, Moonhead, and Pea", these being nicknames Jessie J and the co-producers/co-writers of the song gave each other: Dr. Luke was "Coconut Man" for his habit of ordering coconuts to the studio, Claude Kelly was "Moonhead" for his large head, and Jessie was "Pea" for her small head.
* DeliberatelyMonochrome: The music video for "Wild".
* DoingItForTheArt: [[invoked]] The message of "Price Tag".
* DoubleEntendre: While "Domino" uses several innocent similes, there's this line:
--> You've got me breathing like I'm running 'cause you're taking me there...
* FlippingTheBird: Jessie J flashes both the middle finger and the inverted-V in "Who's Laughing Now".
* FemaleEmpowermentSong: "Do It Like A Dude" is usually interpreted as one of these towards [[TheLadette ladettes]].
* GirlPosse: A younger version is shown tormenting Young Jessie J in "Who's Laughing Now".
* TheGloriousWarOfSisterlyRivalry: The youngest of three sisters, Jessie J describes herself as the odd one out growing up with two academically minded sisters whilst being more inclined toward singing and arts.
* GodIsLoveSongs: "Thunder" is one of them, according to Jessie J herself.
* HiddenDepths: Before her debut single was released, she was getting praise from various other artists who described her as the "best singer in the world," " a musical genius," etc. Before becoming a solo artist, she wrote songs for Music/MileyCyrus, Music/ChrisBrown and Music/JustinTimberlake.
** Her debut single "Do It Like A Dude" was written for Music/{{Rihanna}}.
* ImportantHaircut: For the better part of two years, Jessie J continuously stated she would shave her head for charity. What's interesting is when she did finally get around to doing it, [[MusicIsPolitics she was on the verge of a new album campaign]]...
* IntercourseWithYou: Under her real name of Jessica Cornish, she released a song called "[[https://www.youtube.com/watch?v=Y-NQY7cNjIc Sexy Silk]]", which is part of the ''Film/EasyA'' soundtrack. It definitely fits the trope. In fact, this is basically her favorite subject -- "Domino", "Wild", "Bang Bang", "Burnin' Up" are just a few of the songs about sex that she's made.
* TheLadette: "Do It Like a Dude" is centered on the "man-dem."
* ITasteDelicious: Video for "Who's Laughing Now".
* LingerieScene: Jessie's in black underwear for most of the "Wild" music video, but in an artistic context. Ditto for the single cover.
* MelismaticVocals
* MsFanservice: She's known for her scantily-clad attire.
* PetitePride: While she wasn't very pleased about the "Jessie J has no boobs" comments circulating around, Jessie did say that she is perfectly comfortable with herself, and that you don't need big breasts to be beautiful.
* PrecisionFStrike: Although Jessie J already curses in both "Do It Like a Dude" and "L.O.V.E.," she drops an F-bomb in the otherwise clean "Nobody's Perfect" for good effect. In recent live versions however, she goes for a PG version.
* SelfDeprecation: Jessie calls out "video hoes" in "Price Tag". In the music video, that line is sung over a brief shot of Jessie in her thug outfit from "Do it Like a Dude".
* SelfEmpowermentAnthem: "Who You Are" is about being okay to be hurt, as long as you BeYourself.
* SingerNamedrop: "J-J-J-Jessie J!"
* SurrealMusicVideo: ''Nobody's Perfect'' has clear ''Literature/AliceInWonderland'' influences, along with a room of clocks, Jessie in black glunk, and other surreal scenes.
* TakeThat: The whole point of "Who's Laughing Now?" at former classmates. It's also directed at those who put her down as children and now act interested because of her fame.
** She also made a TakeThat at Birmingham City Council on her social networking pages, although there is doubt over the authenticity of the TakeThat at them.
* ThreeMinutesOfWrithing: Downplayed because it's not as fanservice-y as most examples, but "Domino" features only Jessie, posing and dancing with various costumes in front of trippy green-screen backdrops.
* TrueCompanions: She is best friends with fellow British singer Music/{{Adele}}, with whom she went to school.
