Natalie Portman has a lot to celebrate in 2011. She's expecting a child with her fiancé Benjamin Millepied, whom she met on the set of 'Black Swan.' He was the choreographer, and Portman can now be identified as the Oscar-winning lead actress after 'The 83rd Annual Academy Awards' (Sun., 8:30PM on ABC).

It was her second nomination and first win, and she was simply glowing in both her pregnancy and the excitement of her win.

"I want to thank my parents ... for giving me my life," she said with a smile. "And for giving me the opportunity to work."

She described the role of the psychologically damaged and emotionally fragile ballerina Nina Sayers as "My most important role of my life." The movie hung completely on her shoulders, and it was only through the strength of her performance that it succeeded so well.
