Natalie Portman Marries 'Black Swan' Co-Star; Poses Nude For Sexy Dior Ad [Photos]

Natalie Portman wed Benjamin Millipied, the father of her 14-month-old son on Saturday.

The 31-year-old married her "The Black Swan" co-star after a two year engagement, according to PEOPLE.

Ivanka Trump and MaCaulay Culkin were two of the celebrity guests that attended the private Jewish ceremony held at a California coastal area known as Big Sur. A source told E! that the location was "totally off the grid."

Millipied is a French dancer who worked as a choreographer on the film. The couple met on set while working together in 2009 and began dating almost immediately.

Soon after the couple announced their engagement, they revealed that they were expecting their first child the following year. Several reports indicated that the pair may have wed prior to the ceremony because the couple wore wedding bands at the Oscars in February.

When a pregnant Portman won an Oscar for Best Actress for "Black Swan" in February 2011, she mentioned Millepied in her acceptance speech, thanking him for giving her "the most important role of [her] life."  Portman also won a Golden Globe for Best Actress for the film.

Portman's wedding ceremony was held at a private residence and guests were told they could not bring cameras or take pictures at the event. Trump, 30, tweeted a picture of herself at the secret location.

Oscar-winning Portman recently posed nude for Christian Dior. The images, photographed by magazine lensman Mario Sorrenti, were taken for the the French fashion brand's upcoming ad campaign. It features Portman topless for two different ads and will appear in several fashion magazines in the fall.
