Nikki Reed & Ashley Greene At Breaking Dawn Part 2 Premiere

While Robert Pattinson and Kristen Stewart made the rounds in Madrid, their co-stars kept busy with the Breaking Dawn Part 2 premiere in NYC. Twihards everywhere finally got the long-anticipated finale to the Twilight Saga when it hit cinemas on Thursday, but we've been more preoccupied with what the film's cast are wearing on the red carpet. Yesterday, starlets Ashley Greene, Nikki Reed, and Elizabeth Reaser bared a decidedly sexier side, with their respective gowns and party dresses. Ashley showed off a moody Donna Karan Atelier gown with a figure-flaunting bustier, while Nikki turned up the glamour in a fringed and beaded Naeem Khan confection. But it wasn't just about the film's leading vampires ladies — celebs like Nicky Hilton, Rachel Roy, and Lindsay Ellingson glammed up to celebrate the final Twilight chapter.
