Congrats to Rumer Willis -- she's scored her first role in a movie without either of her parents. (The umbilical cord has been cut at last!) Rumer has signed on to star in a comedy with Katherine McPhee about sisters in the "lamest sorority on campus," according to The Hollywood Reporter. (Katherine plays a pregnant hippy, while Rumer's character won't take off her unnecessary backbrace.) The movie will be produced by Adam Sandler's Happy Madison productions.
