Stepping out for an exciting evening, Emma Watson attended the Hollywood premiere of her new flick "The Perks of Being a Wallflower" last night (September 10).

The English hottie wore a simple-yet-sexy beige backless lace dress as she posed for the paparazzi outside the ArcLight Cinerama Dome.

Emma was joined by fellow famous folks like Nina Dobrev, Ezra Miller, Jackson Rathbone and Shailene Woodley at the star-studded affair.

Prior to the premiere, Watson tweeted to her fans, "If you guys have a free hour at 6:30 come to the Cinerama Dome Sunset Boulevard and celebrate the Hollywood Premiere of 'Perks'. C u there! I think we have 10 tickets to give away to the movie...."
