Natalie Portman and Mila Kunis are about to live out every little girl's (and quite a few big girl's!) dream. The actresses are set to star as competing ballerinas in Darren Aronofsky's film Black Swan, which features scenes from "Swan Lake" where the girls will dance in custom-designed costumes by Rodarte! Already a red carpet fave of Portman's (right), designer sisters Kate and Laura Mulleavy are famous for their ethereal meets gothic designs and incredible use of tulle. So while the girls will be battling on screen for the best grande jete, we doubt they will be fighting over the sure-to-be fantastic costumes!
