Eek! There’s a baby on the way for this famous star!

It has been reported that Rachel Bilson is expecting her first child with her fiancé, Hayden Christensen.

The O.C. star is said to be delighted, with a source saying: “They’ve both talked about this for a while and are so excited. Everyone is beyond thrilled for them.”

Rachel has been dating the Star Wars veteran since 2007 and got engaged in 2008. They went through a bad patch in 2010 but got back together briefly afterwards.

Rachel has always been open about wanting a big family and has said in the past: “I definitely have family on the brain. Having kids is something I want to see in my future – I hope.”

Congratulations to Rachel and Hayden on their happy news!
