'Black Swan' Star Natalie Portman 'Indescribably Happy' About Engagement

Portman recently became engaged to boyfriend Benjamin Millepied and they're expecting their first child together.

It seems as though Natalie Portman has had a most festive holiday season, both on professional and personal levels. Not only is her film "Black Swan" garnering rave reviews and award nominations galore ("Swan" received four Golden Globe nominations, among others), but the petite actress recently became engaged to boyfriend Benjamin Millepied, with whom she is expecting her first child.

"I have always kept my private life private but I will say that I am indescribably happy and feel very grateful to have this experience," Portman gushed in a statement to Entertainment Weekly.

Portman and Millepied met during production of "Black Swan," for which Millepied was the choreographer and played the role of Portman's dancing partner. The two have remained quiet about their relationship, but reportedly started dating in early 2010. Millepied told Details magazine he was "blown away" by her acting abilities and that she was "amazing to watch," but didn't go into any details about their relationship. "It's ... everybody's asking us," he said. "We just want to keep things to ourselves."

The 29-year-old's baby is due sometime in 2011. In addition to her inevitable awards season appearances, Portman has several movies coming out in the new year, including "No Strings Attached" with Ashton Kutcher, "Your Highness" opposite Zooey Deschanel and James Franco, and summer blockbuster "Thor."

Portman's happy news comes at the same time as other romantic celebrity announcements including Daniel Craig and Rachel Weisz's stepping out publicly as a couple and the engagements of LeAnn Rimes and Eddie Cibrian and Ginnifer Goodwin and Joey Kern.
