Mila Kunis has a lasting reminder of her gruelling ballerina training for acclaimed new thriller "Black Swan," she still has her dance partner's thumb marks imprinted on her skin.
The actress plays a professional ballet star opposite Natalie Portman in the Darren Aronofsky movie, which tells the story of a gifted dancer who cracks under pressure after landing a leading role.
Kunis and Portman trained for months before they began shooting, and both dropped a huge amount of weight to look like real ballerinas.
The "Family Guy" star has now revealed the tough preparation has left her facing a medical procedure to remove marks on her body caused by hours of practising lifts with a male dancer.
She tells Britain's GQ magazine, "I thought they would go away, but they haven't, so I'm getting them removed. It's kind of awesome."
