Natalie Portman is having quite the year between winning a Golden Globe, having a No. 1 movie, 'No Strings Attached', and being engaged to her 'Black Swan' co-star Benjamin Millepied and pregnant with his child. So who is the man behind the woman? ET gives you an in-depth look into the life of Portman's new love interest and her future husband.

Millepied (pronounced MEEL-pee-yeh), 33, was born in Bordeaux France and started ballet training at the age of eight with his mother Catherine, according to the New York City Ballet website. "In France, ballet is on TV," he told Details magazine in their June 2010 issue. "It's on the eight-o'clock news. It's a cool thing to be a dancer."

After going to the renowned Conservatoire National dance school in Lyon, France when he was a teen, Millepied ventured to New York City in 1992 for a summer program at the School of American Ballet, the official school of the New York City Ballet. From there, Millepied worked his way up from a member of New York City Ballet's corps de ballet in 1995, to a soloist in 1998, to a principal dancer in 2002. He later went on to directing and doing choreography as well.

In 2007, he received the United States Artists Wynn Fellowship, and in 2010 was made Chevalier in the Order of Arts and Letters by the French Ministry of Culture.

Prior to appearing opposite Portman in 'Black Swan,' Millepied had already danced in Peter Martins' Swan Lake. According to USA Today, Millepied was only asked to choreograph the dances of 'Black Swan' but volunteered himself to play the role of Portman and Mila Kunis' dance partner in the movie. "I really, really got into it," Millepied says. "You're standing up next to those actors, like Natalie, and you're like, '[expletive].' " he told Details. "I was blown away-- especially by Natalie, who was amazing to watch."

Portman thanked Millepied in her Golden Globes acceptance speech saying, "Benjamin choreographed the film, and also you might remember him in the movie as the guy when they ask, 'Would you sleep with that girl?' And he's like, 'Pffsh, no.' He's the best actor. It's not true: He totally wants to sleep with me!"
