Rachel Bilson is pregnant.

The Hart of Dixie actress and her longterm boyfriend Hayden Christensen are "so excited" to be expecting their first child together. "They've both talked about this for awhile and are so excited. Everyone is beyond thrilled for them," a source said.

Friends are delighted for the couple and think they will be "wonderful" parents. "They will make wonderful, hands-on parents," one pal said.

It is not yet known when the baby is due.

The 32-year-old actress admitted last year she was keen to start a family with the Star Wars actor: "I definitely have family on the brain. Having kids is something I want to see in my future - I hope."
