* FreudianSlip: While Cheryl has her below mentioned InsistentTerminology, she catches herself in her thoughts about to say she wants to be a "g-", quickly correcting herself to "anime girl".

** Miyuki of ''Anime/SmilePrettyCure'' has a very poor time keeping her secret identity... and the secret identities of her teammates.

* One of the characters in ''WesternAnimation/LittleDogsOnThePrairie'' is this. The second he's told a secret, he blurts it out for all to hear.

* Linda Belcher from ''WesternAnimation/BobsBurgers'' can't keep a secret at all. Sh once informed a friend of her's their plan to trick their landlord into selling the wharf... behind said landlord's back... and not really whispering at all. When Bob sets a trap to find out who has been ruining all his Thanksgiving turkeys and tells Linda about a second turkey, she told everyone else behind Bob's back, making finding the culprit with the trap AllForNothing.

* ‘’WesternAnimation/{{Amphibia}}'':

* ''Amphibia'':

** It's also a RunningGag that Arthur's best friend Buster just ''cannot'' keep a secret -- whenever Arthur tells him a secret, he'll promise to keep it and then promptly loudly inform the person closest to them that he's got a secret to tell them. When Arthur is ''[[ImStandingRightHere still standing right there]]''.

* The end result of ''WesternAnimation/BarbieAFairySecret''. Following Barbie and Raquelle's big adventure discovering fairies in disguise lived among them, Raquelle wants to tell everyone else, but Princess Graciella insists they keep the fairies and Gloss Angeles a secret. When Raquelle proves not to be a good secret keeper, Graciella sends her, Barbie and Ken home with [[LaserGuidedAmnesia their memories of the fairies and Gloss Angeles erased]], [[OrWasItADream thinking it was a dream]], so [[StatusQuoIsGod the fairy secret can be kept secret once more]].

-->'''Hagrid:''' I shouldn't have told you that.

* In ''Film/Shazam2019'', [[TheBabyOfTheBunch the 8-year-old Darla]] accidentally learns that [[{{ComicBook/Shazam}} Billy Batson]] has superpowers, prompting this discussion as they scramble to hide the fact. [[spoiler:[[RedHerring Fortunately]], aside from [[KeepingSecretsSucks some brief nervousness from staying quiet]], Darla successfully keeps it to herself before others piece it together on their own.]]

* Creator/MarkRuffalo is easily the second-worst offender after the aforementioned Holland, most notably when he [[https://twitter.com/i/moments/918274530182815744 accidentally bootlegged]] ''Film/ThorRagnarok'', and then, while promoting ''Film/AvengersInfinityWar'' with Creator/DonCheadle, he [[https://www.youtube.com/watch?v=_A0UeT38CLo nearly revealed]] that [[spoiler:half the cast dies at the end]]. It got to the point where he received multiple, completely different scripts during the filming of ''Film/AvengersEndgame'' as a precaution by Marvel Studios just in case he accidentally spoiled something.

* Rudy in ''Webcomic/{{Rain}}'' is known to be bad at keeping the secret that his sister Maria is a lesbian, among other slips.

* Cameron from ''[[WesternAnimation/TotalDrama Total Drama Revenge of the Island]]'', who accidentally tells first [[{{Jerkass}} Scott]], then [[TheCutie Zoey]] about Mike's [[SplitPersonality multiple personalities]], though it only does damage the first time as Mike reveals them himself to Zoey soon afterwards.

* The late-Victorian/early-Edwardian socialite Daisy Grenville, Countess of Warwick, was nicknamed "Babbling Brooke" because her husband's [[UsefulNotes/KnightFever courtesy title]] (before he became Earl of Warwick) was Lord Brooke and, well, she babbled. A very well-connected woman who, besides being married to the eventual Earl of Warwick, was TheMistress of [[UsefulNotes/TheHouseOfWindsor the Prince of Wales and eventual King Edward VII]], she was privy to a great chunk of the dealings of the British upper crust. Unfortunately for all involved, she had a habit of telling anyone who would listen the latest bit of juicy gossip, including much that was embarrassing to her husband and her lover. It should surprise no-one that when the Prince of Wales fially broke up with her, her loose tongue was one of several reasons why.

* ''WesternAnimation/SpongeBobSquarePants'': Patrick Star is too dumb to keep a secret. In fact, it was thanks to him that Mr. Krabs found out where their hiding place.

* ''Franchise/PrettyCure'':

** Pinkie Pie -- a MotorMouth and {{Cloudcuckoolander}} extreme -- surprisingly averts this trope in a later episode, "The One Where Pinkie Pie Knows." She's tasked with keeping a huge secret and spends the entire episode trying (and failing) to avoid situations that might tempt her to blab. Pinkie comes dangerously close to cracking several times, but manages to hold in the news until it was officially revealed (though the pressure literally [[VisualPun breaks her apart]] in the end).

* Creator/DanSouthworth is known as the Tom Holland of Devil May Cry for his inability to keep secrets. His biggest blunder was revealing ''VideoGame/DevilMayCry5'' existed all the [[https://twitter.com/kiryuattorney/status/1271509559505453067 way back in 2015]] followed by Creator/ReubenLangdon attempting damage control. Then there were two separate conventions(2007 before [=DMC4=] and 2015 before [=DMC5=]) where Dan introduced Creator/JohnnyYongBosch as [[Characters/DevilMayCryNero his son]].
