Brittany Snow is Cobalt Cute

Brittany Snow is glamorous in a floor-length Leanna Marshall for Diane von Furstenberg cobalt gown at the InStyle/Warner Bros after-party at the Beverly Hilton Hotel in Beverly Hills on Sunday night.

The 22-year-old actress hung out with good friends Zac Efron, Vanessa Hudgens and Amanda Bynes at the party.

Brittany is currently filming Clock Tower, out later this year. The movie is about a woman who is tormented by an evil that has haunted her family for generations, but the only man who believes her is the psychiatrist she meets in a mental institution.
