Gerard Butler Admits He Hooked Up With Brandi Glanville—Watch the Clip!

Chasing Mavericks star also tells Howard Stern he called the reality star to apologize

Perhaps Brandi Glanville's book jogged Gerard Butler's memory?

Last year, the Real Housewives of Beverly Hills star confessed to Andy Cohen that Gerard Butler was the most famous person she'd ever slept with during an appearance on Watch What Happens Live.

But when TMZ cameras caught up with Butler shortly after Brandi's TMI comments and informed the Playing For Keeps star that the mother of two rated him an 11 out of 10 in the bedroom, the actor simply replied "Who's Brandi Glanville?"

Probably not the response Brandi was hoping for.

But now, Butler has set the record straight, admitting to Howard Stern that he did sleep with Glanville, but never learned her last name or what she did for a living, so he was completely taken off guard when questioned by the paps. 

Although the Chasing Mavericks star also admits he was less than pleased the former model went public with their hookup, he did tell Howard Stern he called Glanville to apologize after the embarrassing incident.

Well, that's not awkward at all.
