After falling in love on the set of Black Swan, Portman and Millepied announced in late December 2010 that they were engaged and expecting. Millepied was Portman's constant companion on the 2011 awards circuit, where she picked up a bevy of statues (including the Best Actress Oscar) for her portrayal in Black Swan.
The resolutely private -- but affectionate! -- couple returned at the 2012 Academy Awards, and quietly debuted new wedding bands.
During her emotional 2011 Oscar speech, Portman called the Frenchman "my beautiful love" and thanked him for giving her "my most important role of my life." They welcomed son Aleph in June 2010.
A Black Swan set source told Us it was "seductive to watch" Portman and Millepied fall for one another. "There was no way the attraction could be missed. I don't think he could help himself -- she's dazzling!"
