Natalie Portman graces the cover of Vogue's January 2011 issue, and the actress looks nearly as graceful as the ballerina she plays in Black Swan.

Of course, Natalie appears to have gained back most of the 20 pounds she lost for the film, but she still looks pretty trim in this shot. Natalie recently revealed that she worked out six days a week, eight hours a day to master her dance moves and shed the pounds, and if you've seen the film, you'll know it paid off!
