Natalie Portman, 29, has gotten engaged to her ballet-dancing beau, Benjamin Millepied, 33, with whom she’s expecting a child. The two met while filming Black Swan — she starred in it as a ballerina, and he not only choreographed the dance sequences but played her dancing partner as well. Milliepied, who was born in France, is also a principal dancer with the New York City Ballet. A wedding date has not yet been announced. This will be Portman’s first child.
