Emma Watson at Perks of Being a Wallflower Premiere

Emma Watson wore an asymmetrical Brood mini to bring The Perks of Being a Wallflower to NYC for an East Coast debut last night. She was joined at the Cinema Society event by her costars Adam Higenbuch, Johnny Simmons, Logan Lerman, Ezra Miller, and Erin Wilhelmi at the city's Crosby Street Hotel. Emma and Ezra were in LA earlier this week for their big West Coast debut. There, Emma told us about her reaction when Perks got a standing ovation at TIFF, and also dished on the "hippie"-like atmosphere on set when she made the movie during the Summer of 2010 in Pittsburgh.

Emma also fit in a stop by Late Night With Jimmy Fallon yesterday. Her interview, which aired last night, was hilarious. Jimmy asked Emma about being the riskiest person to search on the Internet. She replied, "My brother says, 'You're about as dangerous as a fluffy bunny.'" Emma and Jimmy also did a silly dance together, and she went on to express love for Pittsburgh.
