Young Hollywood is on the scene at the 10th anniversary bash for Teen Vogue's (appropriately-titled) Young Hollywood Edition, where young hot stars like Victoria Justice, Sarah Hyland, and Oscar nominee Hailee Steinfeld are in attendance! We also run into producer Judd Apatow, but don't get the wrong idea -- he's on hand to support his daughter, a terrific writer in her own right, Maude Apatow! Hosted by Lesley Robins (@lesleymia)
