Emma and Nina Premiere The Perks of Being a Wallflower Hand in Hand

Emma Watson hit the red carpet in Armani for her The Perks of Being a Wallflower premiere in LA last night. She posed hand in hand with her costar Nina Dobrev, who donned a sexy Reem Acra dress, along with the rest of the Wallflower crew, Kate Walsh, Dylan McDermott, Ezra Miller, and Jackson Rathbone. Ezra even brought a cardboard cutout of Logan Lerman, who wasn't able to make the star-studded affair. Shailene Woodley was on hand to lend her support for the film as well. We caught up with all the celebs at the premiere — stay tuned for the video later today on PopSugar Rush.

The West Coast premiere was the latest stop on Emma's promotional tour. She linked up with Nina to premiere the film at the Toronto International Film Festival this past weekend, and last week stopped by the Late Show in NYC to chat about the coming-of-age film. Emma also hit the MTV VMAs last Thursday, and will grace the cover of Glamour's October issue.
