Natalie Portman is pregnant! Natalie Portman is also engaged to her unborn baby's father, Benjamin Millepied! What a day of announcements for her!

The happy couple met during the production of Black Swan, for which Nat earned nominations for a Golden Globe and Screen Actors Guild Award.

Here's a photo of the pregnant and engaged star with her man ...

The future Mr. & Mrs. Benjamin Millepied!

Benjamin Millepied served as choreographer for Black Swan, but a few months into filming, he found himself on the other side of the camera as well.

Of being cast as the dance partner of Portman and co-star Mila Kunis, he said, "I really, really got into it... I was blown away, especially by Natalie."

Apparently! This will be the first marriage for both and their first child as well. It's unclear how along Natalie is, but in any case, congratulations!

For a glimpse of them working together, watch the trailer for Black Swan ...
