Simba: Phuh! You can't do anything to me!

An Idiotic Partner Confession is a situation that begins with Alice keeping a secret from Bob. It could be something she's done, something she's planning or just something she said earlier that she really doesn't want to tell Bob. The problem is, Carl is also aware of this secret, and just happens to be an idiot or has Loose Lips or whatever. So what does Carl do? He starts talking about it right in front of Bob, if not directly to him, of course!
This will undoubtedly lead to Alice trying as discreetly as possible to get Carl to shut up, with Carl completely oblivious that he's saying anything remotely wrong. This will likely piss Bob right off, and lead to all sorts of trouble for poor Alice.
Bob can be a villain, some sort of parental figure, or anyone else who Alice would have any reason not to be honest with. Carl doesn't necessarily have to be an idiot to do this — just unaware of Alice's nervousness or oblivious to the situation.
Different from Right Behind Me, although the tropes might overlap. Compare Accidental Public Confession and Underling with an F in PR. Subtrope of Saying Too Much. See also I'll Never Tell You What I'm Telling You! for purely self-inflicted examples.
