Natalie Portman breaks silence on 'Black Swan' dance double row

Natalie Portman has finally broken her silence about the controversy surrounding 'Black Swan' dance double''s claims that she only did a small portion of the dancing in her Oscar-winning performance.

"I know what went on. And we had an amazing experience making the movie and I don''t want to tarnish it by entering into nastiness," Fox News quoted Portman as telling E! Online.

"I''m really proud of everyone''s work in the movie and my experience. I''ll have that forever. So it''s nice for me to always know about that no matter what kind of nastiness or gossip is going around,� she added.

Last month, American Ballet Theatre soloist Sarah Lane told Entertainment Weekly that Portman performed approximately 5 percent of the dance scenes in the film, while she did the rest.

Lane added that the film''s producer, Ari Handel, asked her not to discuss her work with the press because the producers wanted to play up Portman''s training and dancing.

Natalie Portman 'superstitious over baby'

Natalie Portman has revealed that she is superstitious when it comes to her baby.

The Black Swan actress who announced that she is expecting last December, explained that her Jewish upbringing is the reason she has such beliefs.

She explained on Access Hollywood: "I think it's a Jewish thing to be kind of superstitious. You don't do any of the baby stuff before the baby arrives."

However, the 29-year-old said that her pregnancy is mostly going well.

She added: "My back is not feeling great right now, sitting for so long. But everything's really great otherwise."

According to sources, Portman has announced to her friends and family that she is expecting a boy.

An insider commented: "They've only told a very small group of family members and friends that they're expecting a son. They are so excited. Benjamin cannot wait to be a father.

"Natalie had a big smile on her face. She looked amazing."
