Golden Globes weekend got off to a starry start at the Buffalo Club in Santa Monica, Calif., where Creative Artists Agency held a private party on the restaurant's garden patio. Jake Gyllenhaal chatted up Jennifer Aniston, and despite his recent breakup, the actor "was in a great mood," a party guest tells us. But the actor spent most of his time talking to his sister Maggie and Peter Sarsgaard. Meanwhile, the 200 guests nibbled on hors d'oeuvres like oysters and Ahi tuna carpaccio on the patio, which was decked out with lanterns and candles. "The patio was absolutely packed and the atmosphere was very glamorous and fun," says a source. "Wherever you turned, you would bump into a big movie star."
• One such star, Gerard Butler, was the first big celeb guest to arrive at the CAA party (at 8 p.m.) – and he also was among the last to leave. "Gerard closed the party past 2 a.m.," a source tells us. "He was very nice and thanked the restaurant for a great time." Butler also chatted up his Bounty Hunter costar Aniston, whom a source describes as a "social butterfly" who mingled with all the guests.
