On April 28, RHONY flauntepreneur Sonja Morgan took a tip from Teresa Giudice and flipped the tables on Watch What Happens Live host Andy Cohen.

During a Q&A, Cohen answered some very personal questions including the most famous person he’s ever slept with. Drum roll, please!

Now, the host with the most didn’t go into detail about how, er, *NSync the two were, but he did reveal a pattern of liking younger guys. In fact his current celebrity crush is Zac Efron (well, he certainly has good taste).

Bass addressed Andy Cohen’s recent apparent revelation that they had sex awhile back on his SiriusXM radio show Dirty Pop on Thursday, May 7 — and pretty much denied that he and Cohen ever had actual intercourse.

“First of all, I’m not going to tell you what I do in the bedroom,” Bass prefaced, before going into his romantic history with the Bravo host. “Sex is a broad term…like ‘Andy banged Lance’ — when did he ever say that? This is an old story. Three years ago we told everyone we hooked up…Now it’s getting into who did who? I can just tell you right now, there was no Andy D going in my B,” Bass candidly admitted, before adding: “I’m not going to tell you what went down…but it’s not what people are thinking.”

Bass explained to US, when he hooked up with Cohen, he had just gotten out of a relationship that ended “terribly.”

“It just happened that Andy was with me on this vacation,” he recalled. “It was so nice and romantic and it was just a nice time. It was one of those things where I needed someone to hold onto.” (The two friends previously admitted to sharing a drunken kiss while on a sailing trip with friends on Valentine’s Day back in 2007.)

“I just played it off like it was a kiss,” Bass admitted of how he previously addressed their encounter. “Why would I go into details?”

Who do you believe?
