`The Real Housewives of Beverly Hills` star Brandi Glanville claims to have slept with the Scottish actor last year, and when asked to rate his sexual prowess claimed he was more than good.
Speaking on `What Happens Live with Andy Cohen`, the 39-year-old blonde was asked who was the most famous person she hooked up with, and responded: "GerardButler".
She added the pair had a "little week of fun", and when asked to rate the `Coriolanus` hunk out of 10, she said, "11".
Despite his reputation as one of Hollywood`s most eligible bachelors - having been linked with Cameron Diaz, Jennifer Aniston and model Sarah Carroll - Gerard has claimed he would like to be in a long-term relationship.
He said: "I would love to settle down and share my life with someone. But it`ll happen when it`s going to happen.
"When I try and plan things in my life they very rarely pan out. And it`s often when I think, `OK, you know what, I don`t want to be in a relationship right now for whatever reason`, that suddenly I find myself open to one and it happens."
