Miss Golden Globe Rumer Willis

In J.Mendel at a Hollywood gala

With parents like Demi Moore and Bruce Willis (not to mention step-dad Ashton Kutcher), it's no surprise that Rumer Willis is a natural It Girl. The up-and-coming actress was appointed Miss Golden Globe in 2008, a role traditionally held by the offspring of Hollywood royalty, when the cancellation of the ceremony led to a postponement of the honor. In the meantime, Willis has had a very stylish year, starring in ensemble comedy The House Bunny, being honored as one of People's Most Beautiful stars and stealing the spotlight with some killer clothes.
