Mila Kunis: 'Natalie Danced Her A** Off' in 'Black Swan' While rumors have been swirling over who really pas de bourree'd their way into our hearts in 'Black Swan,' Mila Kunis is speaking out on behalf of 'Swan' co-star Natalie Portman, saying that the actress deserves recognition for her hard work in the film's dance numbers.

Last week, dancer Sarah Lane, a soloist with the American Ballet Theatre, claimed that she had provided most of the footwork for which Portman was credited. "Of the full body shots, I would say 5 percent are Natalie," said Lane. "All the other shots are me."

Kunis vehemently denies Lane's report, saying, "Natalie danced her a** off. I think it's unfortunate that this is coming out and taking attention away from [the praise] Natalie deserved and got."
