Rumer Willis @ EW Pre-Emmys Party

Rumer Willis plays up her fit figure at Entertainment Weekly‘s 5th Annual Pre-Emmy Party at Hollywood’s Opera/Crimson on Saturday.

The 19-year-old daughter of Bruce Willis and Demi Moore has been busy filming I Know What Boys Like with BFF Idol Katharine McPhee. In the film, Rumer plays an insecure young woman who wears a backbrace even though she could have had it removed years ago.
