Amy Schumer overshares about Jennifer Lawrence's bathroom habits: 'She sees a bidet, she's gonna piss in it'

A true-blue friend is someone you can always count on for complete honesty, and Amy Schumer apparently holds nothing back when it comes to her bestie Jennifer Lawrence.

Vanity Fair's latest cover girl played a fun game of truth-telling for the magazine as she responded to her 25-year-old pal's pre-taped interview responses.

When the subject of bidets came up – Jennifer infamously pretended to pee in one in a Facebook video gag last year – Amy, 34, was brutally hilarious.

"That girl, she sees a bidet, she's gonna piss it in," Amy revealed, before riffing on the "regal" function of bidets.

In the Vanity Fair video, Amy also talked about how they met (J-Law emailed her after seeing Trainwreck) and the upcoming movie they're writing and acting in together.

But what we really want to know is this: Is the J-Law-from-the-block act for real?

"Jen is the meanest person I know," she joked (we hope), adding, "Jen has sent me so many hurtful texts that make me laugh. We write each other into the script…I'll write character descriptions of each other, so I'll be like, 'This troll from Kentucky…'"

Jennifer is Kentucky-born, but Amy had to be kidding. Right?

We wonder what Jennifer thinks of Amy's glamorous Vanity Fair cover-girl pose. Erm, who's "plus-sized"?
