Paging McDreamy: Do you know your fiancee is pregnant? Not really -- just the actress who plays her.

Ellen Pompeo, who plays Dr. Meredith Grey, the future bride of Dr. Derek "McDreamy" Shepherd on "Grey's Anatomy" and her real-life love, Chris Ivery, are expecting their first child together.

Pompeo's publicist, Jennifer Allen, did not give a due date.

The 39-year-old actress and Ivery, a record producer, are one of Hollywood's low-key couples. After three years of dating, they quietly tied the knot in November 2007 in a ceremony at New York City Hall.

Pompeo heads an ensemble cast on the ABC series. This season, Shepherd finally proposed to Grey, satisfying fans who've hankered to see the star-crossed surgical duo walk down the aisle.

Congrats to Ellen and Chris ... and may the bump-watch begin!
