Mila Kunis has come to the defence of Natalie Portman.
Allegations have flown around this week about the movie as dancer Sarah Lane, Portman's double, suggested that the actress only 5% of the full body shots.
Director Darren Aronofsky has already waded into the argument insisting that of the 139 dance shots in the film 111 are Portman.
And now co-star Kunis has also had her say.
Speaking to Popeater the actress said: "I think it's unfortunate that this is coming out and taking attention away from [the praise] Natalie deserved and got.
"[Lane] wasn't used for everything. 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 went on to pick up her first Best Actress Oscar for her stunning performance in the movie and Black Swan was also nominated for Best Picture, losing out to The King's Speech.
