Rachel Bilson is pregnant

Rachel Bilson's latest role? Motherhood.

Multiple sources have told Us Weekly that the "Hart of Dixie" actress, 32, is pregnant. This will be the first child for her and longtime boyfriend Hayden Christensen ("Star Wars," "Life as a House").

"They've both talked about this for awhile and are so excited," a "Bilson insider" told the magazine. "Everyone is beyond thrilled for them."

Bilson and Christensen, 33, met in 2007 on the set of the film "Jumper." The pair, who has mostly kept their romance out of the spotlight, got engaged in December 2008 but then split in August 2010 before reconciling three months later.
