Alexander Payne’s celebration after “The Descendants” won best drama at the Golden Globes on Sunday night was muted — literally. The director was at Fox’s after-party wearing pink earplugs and telling guests he was wearing them to protect his sensitive ears from people shouting over the loud music. The move didn’t dissuade the throngs at the packed party from congratulating him. Also at the bash, held in a tent at the Beverly Hilton, was “Glee” creator Ryan Murphy. Michael Fassbender mingled with the glam crowd while puffing on a cigar (which was aptly large after George Clooney’s acceptance speech mentioned Fassbender’s endowments as an actor). The cast of the night’s winner for best dramatic series, “Homeland,” celebrated their triumph with a dance-off. “Modern Family” star Sofia Vergara arrived with her boyfriend Nick Loeb, who joked that he’d smuggled in a condiment he’s promoting, called Onion Crunch, to sprinkle on the canapes. Astonishingly, shapely Vergara said, “I eat it on pizza — that is how I keep this body.”
