During an appearance on The Oprah Winfrey Show, Natalie Portman was surprised when Oprah pulled out an old clip of her performing in a stage production of Cabaret during her childhood days at drama camp. But that’s not the embarrassing part. In the clip, one of the other dancers takes a NASTY spill off a chair! You really have to be feel sorry for that poor girl. Under normal circumstances, she’d probably be able to put that embarrassing fall behind her. But because she just happened to be dancing next to Natalie Portman, her moment of infamy would up being broadcast in front of millions of people.
