Ashley Greene steps out on the red carpet in a little black dress with a full ruffle skirt at the premiere of Twilight at Mann Village’s Bruin Theater on Monday night in Westwood, Calif.

The 21-year-old actress was taken aback by the fans’ screams at the premiere. She told USA Today, “It’s a dream. It’s like a fairy tale. I was an unknown, you know?”

Ashley plays Edward Cullen’s vampiress sister, Alice Cullen. Jackson Rathbone (also pictured below) plays Jasper Hale, Alice’s husband.
