Natalie Portman may have won her first Oscar for her physically demanding role in 'Black Swan,' but the actress has recently been criticized for all the fanfare when it was revealed she had a dancing double in the film. Her fiance, Benjamin Millepied, is now coming to her defense on the dancing matter.

"There are articles now talking about her dance double [American Ballet Theatre dancer Sarah Lane] that are making it sound like [Lane] did a lot of the work, but really, she just did the footwork, and the fouettes, and one diagonal [phrase] in the studio," Millepied told the Los Angeles Times.

Millipied served as the choreographer for the psychological thriller, as well as performed as one of the dancers in the film.

"It was so believable, it was fantastic, that beautiful movement quality," Millepied said of Portman's dancing. The actress famously trained for a year to accurately portray a professional ballerina in the film.
