After the awards ceremony, the stars flocked to the annual InStyle/Warner Bros. after-party at the Beverly Hilton Hotel. Best Actor and Actress winners Robert Downey Jr. and Sandra Bullock congratulated each other with trophies in hand. The party was Bullock’s only stop for the night, but she was determined to make it count. “We’ve got about another hour in us and then we’re going home,” said Bullock, who was accompanied by husband Jesse James. Other guests included Cameron Diaz, Kate Bosworth and Ashley Olsen, who celebrated boyfriend Justin Bartha‘s Best Comedy win for The Hangover.
