Glanville, who made a spectacle of herself in a low-cut dress at the Oscars in February, revealed she had hooked up with Butler last year – rating him 11 out of ten for his bedroom prowess.

Now Butler has confirmed her claim in a chat with shock jock Howard Stern. He told the DJ: “We crossed paths at a beach party and had a little bit of fun.”

He then added: “Suddenly, one day a paparazzo runs in my face and says, ‘So Brandi Glanville says you’re great in bed!’ You know what I said? ‘Who is Brandi Glanville?’ One, I didn’t know her last name. And two, I didn’t know she was a celebrity."

He later called her to apologize for not knowing who she was. Butler told how he confronted the Real Housewives of Beverly Hills beauty, saying: “I said, ‘One, I’m not very happy you did that because there are certain things you keep a little private.’

And two, ‘I’m sorry I said I didn’t know who you were.’”
