Also co-hosting was Entourage star Adrian Grenier, wearing a spiffy black suit, red tie, red Converse sneakers and a bit of a scowl. So what are next season’s plot developments? “There’s not going to be a next season!”huffed the HBO heartthrob. “You write to your studio and tell them to give more to the writers and stop hoarding all the money for themselves!” O.K.!

In the crowd: MTV host Damien Fahey, actor Michael Pitt, director Terry George, musician Moby, and cuddly designer Isaac Mizrahi with his boyfriend Arnold Germer, an actor. “Arnold and I are so looking forward to just going to Bridgehampton with our kiddies [dogs] Dino and Harry, and I’m looking to go on an eating binge,” Mr. Mizrahi said of his holiday plans. “Even though I shouldn’t really do that!” Any Christmas wishes? “I won’t even say! I have my heart set on something but it’s too late!I’m not even going to ask because he won’t get it for me!”
