Pictures of Roger Federer, Bar Refaeli, Bradley Cooper, and Rafael Nadal at Knockout Tennis Tournament

Bradley, Bar, Rafael, and Maria Match Up For Tennis in NYC

Bradley Cooper and Bar Refaeli joined tennis pros Maria Sharapova and Rafael Nadal for a doubles match at the Nike Knockout Event in NYC yesterday. Serena Williams, who wore a brace from her recent foot surgery, and Roger Federer were also on hand for the exhibition games. Bradley showed off his skills, and while he kept his shirt on during the match, he's still one of this Summer's most memorable shirtless movie men. Bar sported a tan from her bikini-filled Italian vacation with Leonardo DiCaprio and looked like a natural with her racket. Meanwhile, Andy Roddick hit the court at a different event to help kick off next week's US Open.
