Mila Kunis has defended co-star Natalie Portman after a dancer who acted as her body double said the actress only performed a fraction of her character's dancing in "Black Swan."
"Natalie danced her (expletive) off," Kunis told Entertainment Weekly. "She did do every ounce of every one of her dances."
Ballet dancer Sarah Lane had said ahead of the DVD release of the movie on March 29 that Portman did "about five percent of the on-screen dancing" in "Black Swan."
In the thriller, Portman plays a troubled and competitive ballerina and Kunis plays a dancer who tries to manipulate her. Portman earned her first Oscar for her role.
Kunis told Entertainment Weekly that Lane "wasn't used for everything," adding: "It was more like a safety net. If Nat wasn't able to do something, you'd have a safety net. The same thing that I had - I had a double as a safety net. We all did. No one ever denied it."
Portman has not commented. Her fiance Benjamin Millepied, a ballet dancer who appears in the film and is the father of her unborn child, the movie's studio, Fox Searchlight and director Darren Aronofsky have all come to her defense following Lane's comments.
Portman told OnTheRedCarpet.com in late 2010 that her parents were supportive of her role in "Black Swan," which sees her sharing a sex scene with Kunis, but that some parts were tough for her mother to watch.
Portman recently starred in the sex comedy movie "No Strings Attached" with Ashton Kutcher, which she has joked may have made her father happy, and appears in the upcoming fantasy comedy movie "Your Highness" alongside Academy Awards co-host James Franco.
Portman plays a warrior who helps a pair of princes, played by Franco and Danny McBride of the HBO series "Eastbound & Down," save a maiden, played by Zooey Deschanel, from an evil wizard, portrayed by Justin Theroux.
The director of "Your Highness," set for release in April 2011, is David Gordon Green, who directed Franco and McBride in "Pineapple Express."
