The pregnancy news was confirmed to Us Weekly.
“They’ve both talked about this for awhile and are so excited,” a source told the mag. “Everyone is beyond thrilled for them.”
Rachel Bilson, 32, and Hayden Christensen, 33, met in 2007 on the set of the film Jumper, and have been a couple since then.
The two went through a temporary breakup in 2010, but they reconciled three months later.
Last year in May, Rachel revealed to Cosmopolitan magazine that she wants to become a mother.
“I definitely have family on the brain. Having kids is something I want to see in my future—I hope,” she said then.
And it seems that her wish was fulfilled.
