Actress Natalie Portman is engaged to a ballet dancer and choreographer and expecting her first child with him, People magazine reported on Monday.

The 29 year-old actress met the French choreographer, Benjamin Millepied, during the production of her newly released movie, "Black Swan," which has earned her Oscar buzz.

Millepied, born in Bordeaux, France, is a principal dancer and choreographer at the New York City Ballet.

In "Black Swan" Portman plays a New York ballerina whose obsession with technical perfection takes a heavy toll on her mind and body.
