Nikki Reed glams up the red carpet in a gorgeous black-and-white patterned Marchesa dress at the premiere of Twilight at the Mann Village and Bruin Theater on Monday night in Westwood, Calif.

The 20-year-old actress topped off her look with Neil Jane jewelry, Rene Caoville pumps and a Kotur clutch. Doesn’t she look fab???

In the film, Nikki plays Rosalie Hale, one of Edward Cullen’s step-siblings in the devilish film. She recently shared the moment when she realized how big the Twilight series really was: “There were fans that were finding out where the locations were, and that’s when it really hit me. People saying, ‘Oh, it’s going to be the next Harry Potter!’ That’s a big mountain in front of you. There’s a lot of hype around this.”
