The US Open drew to a close last night with a dramatic match in which Juan Martin Del Potro defeated Roger Federer as another celebrity-filled audience looked on. There were a lot of loyal tennis fans around like the Stefani-Rossdales, who looked sad after their friend's loss, and the Olsen twins, who sat together this time around. Bruce Willis brought his young wife Emma, and Anna Wintour came by again after taking home a tennis ball over the weekend. She had to slip out a few minutes early, however, to make it to Marc Jacobs's show on time. The manjoyment factor was high in the stands with hotties Jake Gyllenhaal, Gerard Butler, and Josh Hartnett as everyone enjoyed the intense men's final.
