Gearing up for the 2010 US Open, some of the hottest stars and top athletes were in the house last night at the Nike Tennis Primetime Knockout event.
Bradley Cooper took to the court at Pier 54 to show off some of his racquet skills, sporting a backwards ballcap and retro-style polo shirt.
Also in the house was Israeli-born supermodel Bar Refaeli who looked to be in fine form as she hit a few balls while wearing a sporty black dress.
And of course, tennis’ best and brightest showed up, including Rafael Nadal, Roger Federer, Maria Sharapova, and Serena Williams.
