Another celebrity is all set to give birth to a bundle of joy. The former "O.C" star Rachel Bilson is reportedly pregnant with longtime partner Hayden Christensen. Though the couple has not made an official statement regarding the pregnancy, reports have it that Bilson is soon to become a mommy.

Rachel and Hayden have been in a relationship since 2007. The couple got engaged in 2008 but called it quits a couple of years later. However, the two later reunited and are now making waves with baby news, reported US Weekly.

Bilson has apparently always wanted to have a family. She opened up about her wish to start family to Health magazine's June issue.

"To start a family would be good, any year in the next few years," said Bilson in the interview adding, "I've always wanted to be a mom. I have always wanted kids. I can just see this little toddler waddling around the house."

Regarding her relationship with Hayden, Rachel had suggested to the magazine that he gives her incredible support.

"He's so incredibly supportive and considerate," said the former "O.C" star to the magazine "I've been in my relationship for seven years, so we've grown up together in a way. This is my partner, my support, just there for me no matter what. And vice versa."

Meanwhile, Bilson was recently seen hiding her baby bump during the CW Upfronts appearance. The former "O.C" star was seen wearing a Mary Katrantzou floral dress, which worked wonders in hiding her bump.

Bilson is currently seen in CW's " Heart of Dixie" and is pretty excited about her upcoming show.

"I guess I felt pretty good because we have a solid thing going at this point and we have so many fun things to play with and it's so different from any other show on the network. I'm lucky with all my co-stars and also Zoe is an idiot and it's fun playing an idiot," gushed Bilson to E! about the upcoming season of the show.
