Howard Stern, as is his M.O., grilled my imaginary boyfriend Gerard Butler about his sex life. Specifically, his sex life with Brandi Glanville. You know, the hot mess whose name he didn't recognize.

Butler described meeting Glanville at a beach party and asking, "What do you do?" She told him it didn't matter.

That means one of two things, generally: celebrity or drug dealer. Red flag, bro!

He continued, "We hung out, we had a little fun. Suddenly, one day, I'm walking down the street and this paparazzo ... runs in my face and said, 'So Brandi Glanville says you're great in bed!'"

"So I said, 'Who's Brandi Glanville?'" Butler admitted, chuckling. "Because I didn't know her last name, I didn't know she was a celebrity -- and I didn't know she was going to f---ing tell people about it."

Watch the clip above to find out how Butler figured everything out -- and what Glanville did when he reached out to discuss the drama.

It's okay, baby. I'd block it from my memory, too.
