PHOTOS: Andy Cohen Takes Kim Kardashian Butt Selfie on #WWHL

Andy Cohen got up close and personal with Kim Kardashian during Watch What Happens Live on Tuesday, Aug. 12. The Bravo host snapped a butt selfie of the Keeping Up With the Kardashians star — and she didn't seem to mind!

"Tonight @kimkardashian let me take a selfie with her ass. #WWHL," Cohen, 46, wrote. In the hilarious moment, Kardashian walked behind a seated Cohen and donned a fitted custom Michael Costello dress.

During the episode, North West's mom, 33, was game to answer several questions about her personal life. She opened up about brother Rob bailing on her Florence, Italy nuptials to Kanye West in May and admitted which of Rob's exes she wouldn't mind calling a sister-in-law. (Spoiler: Adrienne Bailon!)

Kardashian also discussed her plans to give North a younger sibling. "I would love baby number two!" she gushed. "We're trying. We're having fun trying!"
