Access Hollywood‘s Billy Bush followed Jennifer Aniston to Mexico and sat down with her to talk about turning 41. “We don’t say that number out loud!” Jen immediately said. So Bush asked how it felt to turn 31.  “Thirty-one, pssh. It’s quite lovely I have to say. Thirty was a hump but you know 31 is fabulous. It really does get better doesn’t it?”

When the topic turned to fellow guest Gerard Butler, who stars with Aniston in the upcoming action comedy The Bounty Hunter, Aniston said that they had a great time working together.

“We just had so much fun together you know. He’s just fun. Gerry’s the most unpretentious guy,” said Aniston. “He’s a guy’s guy, but he’s absolutely the most lovely and sort of self-deprecating …  and just what you see is what you get. We look at work the same way…we always had each other’s back.”  Billy’s multi-part interview starts airing tonight on Access. – Ann Oldenburg
