Don't Miss:

Emma Watson certainly stepped away from the wall last night, as she shone alongside co-stars Ezra Miller and Erin Wilhelmi in a white BROOD mini (an up-and-coming brand she loves!) at The Cinema Society and Lancome’s screening of her new film The Perks of Being a Wallflower at the Crosby Street Hotel in New York. The actress talked about how she got into her role of Sam for the film: “By just asking a load of questions, and talking to [co-stars] Ezra [Miller] and Logan [Lerman] about their high school experiences.” Catch the movie in theaters September 21, and click through the gallery to see more stars from last night’s biggest events.
