Jennifer Aniston Gushes About Gerard

It’s no secret they have a great connection and Jennifer Aniston admits that she enjoys being around Gerard Butlersimply because he’s relaxed and fun.

The “Bounty Hunter” star said, "We just had so much fun [making the movie] together, you know. He's just fun. Gerry's the most unpretentious guy. He's a guy's guy," she adds, "but he's absolutely the most lovely and sort of self-deprecating [person] and just what you see is what you get. We look at work the same way … We always had each other's back."

40 year-old Butler joined Aniston and friends in Los Cabos, Mexico for the actresses’ 41st birthday celebration where there was only one rule: no one could say 41 out loud. Of getting older, Jen jokes, "Thirty was a hump, but you know 31 is fabulous. It really does get better, doesn't it?"

Why Cabo for her bday festivites? “These people survive on us coming down and spending money," Aniston explains. Considering the country's troubles with swine flu and drug trafficking, "It sort of made sense to sort of say, 'Hey, let's help out Mexico.”
