Things escalated quickly on Thursday night’s Watch What Happens Live, featuring DNCE’s Joe Jonas. He started playing a harmless game of “Plead the Fifth” that led to this scandalous question: Which Jonas Brother is most — wink, wink — “well-endowed?” (Host Andy Cohen asked Nick Jonas the same question weeks ago, but he refused to answer.)

“You know, these were Nick’s words, not mine, but he said he was going to say me,” Joe said, “so I'll say me.” How humble.

The intimidating questions didn’t end there. Joe went on to play “Shag, Marry, Kill” with his ex-girlfriends Taylor Swift, Demi Lovato, and Gigi Hadid.

“I’ll marry Demi, she’s a friend,” Joe said. So who he’s gonna shag and kill — Taylor or Gigi? It was a tough decision, as you can tell from the video below.

Man, talk about putting someone on the spot.
