Rumer Willis @ Superbad Premiere

Rumer Willis throws on a sequined minidress and a fedora at the premiere of hilarious high school comedy Superbad held at Hollywood’s Grauman’s Chinese Theatre on Monday night. The actress finished off her look with a pair of rainbow-sprinkled pumps and the Balenciaga Quilted Small Bag from the Fall-Winter 07/08 collection.

The actress, who turns 19 on Thursday, recently explained the backbrace photo to People: “That picture was taken from a photo shoot we did for the movie for a calendar in the film that shows [the sorority girls] going too far. Somebody happened to take a picture and leak it. It is what it is.”

Rumer also expressed interest in breaking into the music industry: “I love a lot of different things. I really like acting, I really like music and I love photography. In a perfect world I could do all three. In the future, I would love to do an album. I have been singing since I was really little which not a lot of people know about so it’s one of those fun, personal things.”
