Mila Kunis and Natalie Portman are gorgeous at the New York premiere of Black Swan last night. This much-hyped, much-anticipated film is in theatres on Friday.

Natalie Portman is Everywhere!

These two beauties ended up losing a lot of weight for their role.  Natalie was a tiny, little thing to begin with.  But after this role was complete, she lost 20 pounds!

Professional ballerina, Mary Helen Bowers was Natalie’s coach of sorts for her training.   She usually put in 8 hours a day with only one day off per week to become the perfect ballerina.  Mary told Us Weekly at the premiere,

“The goal was to create a very long, lean ballet-type body. We combined swimming a mile a day with two hours worth of Ballet Beautiful exercises, toning, and resistance work. And another 3-plus hours of ballet class and point work.  We were working at 5 in the morning for two or three hours, and she worked a 12 to 14-hour day on set.”

Talk about being committed to a role!  I would be into that for a day or two.  Then I would just hide in a corner, hugging my pillow, crying for my mommy!  Natalie Portman is Amazing!  With a capital A!  I am really excited to see this film!
