In a special one-on-one interview with Andy Cohen, Real Housewives of New York star, Sonja Morgan, asked the Bravo producer who his most famous celebrity hook up was. The Watch What Happens Live host admitted to sleeping with Lance Bass but the former NSync member denies anything like that ever happened.

After Cohen told Morgan on Tuesday about his relations with the singer, Bass went on his SiriusXM radio show, Dirty Pop, and told listeners that it isn't true.

"First of all, I'm not going to tell you what I do in the bedroom," the radio host said. "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."

Michael Turchin's husband stuck to the don't kiss and tell motto and said, "I'm not going to tell you what went down...but it's not what people are thinking,"
