Courtney Cox cools off

Courtney Cox got wet and wild  in a teeny-weeny two-piece while filming Cougar Town in Hawaii on Wednesday. She credits plenty of gym time for her fab physique. "Some people might not want to show the parts of them that aren't the best but I work out really hard," says Cox, who has trained with celeb fitness guru Tracy Anderson. "I try really hard." It's paying off. Costar and rumoured beau Brian Van Holt took notice. During the shoot, the pair had separate rooms but "Brian went in and out of her suite four times a day," a source tells the new issue of Us Weekly. However, a Cox pal insists the two are just friends.
