Whether we wanted to or not, we now know which ‘NSYNC member got the most action.

The news is courtesy of Lance Bass’ revelation on a recent episode of Watch What Happens Live.

The singer appeared on the Sept. 12 episode of the show and played a game of Truth or Tweet.

When Andy Cohen asked, "Which member of 'NSYNC has had the most sexual partners?" A shocked Bass took a second and then gave us the answer.

“I mean, Chris Kirkpatrick — he’s a Casanova!” Bass revealed. “You know, before. He’s married to a lovely wife now but ya know, he was single for a while.”

And that wasn't the only scandalous 'NSYNC question Cohen had for him. He also put Bass on the spot by asking him which bandmate he would never sleep with himself.

“Who would I not have sex with?" the 37-year-old pondered before answering, "I wouldn’t have sex [with] Joey Fatone. I don’t know, yeah, take that.”

Aw, sorry Joey.
