Joe Jonas paid a visit to Andy Cohen's Watch What Happens Live last night alongside Ashley Graham, the model who plays his love interest in DNCE's sexy "Toothbrush" video. And like his brother Nick Jonas, who guested on WWHL back in June, he was subjected to a round of overly-personal questions for our amusement — including a round of "Shag, Marry, Kill" involving his famous exes Taylor Swift, Demi Lovato and Gigi Hadid.

But first, Andy asks during Plead the Fifth: "Which JoBro is the most well-endowed?"

"You know this is Nick's words not mine, but he said he was gonna say me. So I'll say me," Joe offers. How diplomatic?

Next, Andy asked a question about an unreleased song that Joe says "is gonna piss someone off." Could it be about his ex Taylor, who of course wrote some scathing songs about him after their breakup (he countered on 2009's "Much Better": "I got a rep for breakin' hearts/ Now I'm done with superstars/ And all the tears on her guitar/ I'm not bitter.")? Sadly, Joe won't say.

"Plead the fifth," the littlest JoBro replied, saying we might hear it as a B-side someday.

Having cashed in his one chance to stay silent, Andy then pressed Joe on is S/M/K picks regarding exes Taylor, Demi and Gigi.

"I'll marry Demi," Joe said, which is less than surprising given he and Nick remain close with their fellow Disney alum. "She's a friend."

Then things got tougher. "It's a game, right?" the "Cake By the Ocean" singer nervously joked. "Ummm..."Um, Shag Taylor? Kill Dem—kill Gigi? There you go."

Andy and Ashley both revealed that until that night, they had no idea Joe and Taylor were in each other's sizable celebrity-ex stables.

"We were children," Joe said. "18, 19."

Who do you think Joe's unreleased song would piss off? Share your guesses in the comments.
