Christian Slater kept his arm around girlfriend (and Jimmy Choo founder) Tamara Mellon all night. Mellon contributed a $100 gift certificate toward an item from her luxe label to the take-home goody bag, which also contained a $100 Saks Fifth Avenue card, a "Dude, where's the cure?" T-shirt from Juicy Couture and must-haves from Tory Burch, Natori and Kenneth Cole.
