Gerard Butler Organized Jennifer Aniston's Birthday Celebration

Guess who is responsible for Jennifer Aniston's birthday celebration in Cabo? Her 'The Bounty' co-star, Gerard Butler.

"He said to me, 'You come to Mexico all the time and Mexico is really hurting right now because of the swine flu and the drug trafficking and all of this sort of stuff but it’s not all of Mexico,'" explained Aniston. "These people survive on us coming down and spending money and coming here to these beautiful places.

"It sort of made sense to sort of say ‘Hey, let’s help out Mexico,'" continued Aniston. "Let's shout out to these kids in Tijuana at El Faro and you know, have a big…that's sort of our birthday celebration this year."

Giving back while sunbathing in luxury? Sounds like a winning combo to me! So what exactly is the nature of Jennifer's relationship with Gerard?

"We just had so much fun together [working on 'The Bounty'] you know. He's just fun. Gerry's the most unpretentious guy," elaborated Aniston. "He's a guys 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."

This must be some friendship for them to be vacationing together (along with other friends :).

So how does Jennifer feel about turning 41?

"Thirty-one, pssh. It's quite lovely I have to say. 30 was a hump but you know 31 is fabulous. It really does get better doesn't it?"

With that body, Jen, you should be PROUD to say you're 41! LOL

Do you think a romance is brewing between Jennifer and Gerard or are they just good friends?
