Mila Kunis won't dance again

Mila Kunis has vowed never to dance again.

The 'Black Swan' actress found training for the ballet-based thriller incredibly intense, and suffered so many injuries and pain from wearing specialist shoes, she claims the finished movie marks the last time she will ever show off the skills she learned.

She said: "I had never danced in my life. I trained for four months, seven days a week, five hours a day. I had one day off on my birthday. I lost 20 pounds. I tore a ligament. I dislocated my shoulder. I have two scars on my back. And it was worth every minute.

"But I will never dance again. I was like, 'Well - I wear heels; I can do this.' I was wrong. Christian Louboutins are uncomfortable, but I screamed the first time I put on a pointe shoe.

"It's great that the performance has been captured on film, because I will never put on those pointe shoes again."

Despite her pain, Mila, 27, was pleased with herself when she watched her performance in the film.

She told the March edition of W magazine: "Before I started, I couldn't even lift my arm properly. I literally had no posture, so, yeah, the first time I saw the movie, my jaw dropped. I was like, 'Oh, my God - I don't suck.' "
