Natalie Portman can now call herself an Oscar winner! The 29-year-old actress won the Academy Award for “Best Actress in a Leading Role” at the Oscars last night (Sun. Feb 27) for her performance as a ballerina gone crazy in the hit movie “Black Swan.”

“Thank you. Thank you so much. This is insane!” the first-time Oscar winner said when she accepted her award. “I want to thank my parents for giving me the opportunity to work from such an early age. My beautiful love, Benjamin, who has now given me my most important role of my life,” she gushed. “Most importantly, my family, my friends, and my love, thank you so much.”

Portman showed off her baby bump in a deep purple dress designed by Rodarte (who also designed the costumes for “Black Swan”) as she arrived on the red carpet and posed for photos outside the Kodak Theater in Hollywood just before the ceremony kicked off.
