'Black Swan' certainly won't be Natalie Portman's swan song.

The actress took home the award for best actress in a leading role at the 2011 Oscars for her role as troubled ballerina Nina Sayers.

"I truly, sincerely, wish the prize was to get to work with my fellow nominees. I'm so in awe of all of you," a pregnant Portman, dressed in Rodarte, said as she accepted the accolade.

Portman beat out Annette Bening for 'The Kids Are All Right,' Jennifer Lawrence for 'Winter's Bone,' Michelle Williams for 'Blue Valentine' and Nicole Kidman for 'Rabbit Hole.'
