Rachel Bilson is pregnant with her longtime boyfriend Hayden Christensen's baby, reports suggest. The couple has been in a relationship for a long time now and is apparently thrilled with the news. 

"They've both talked about this for awhile and are so excited," an insider told US Weekly, adding "Everyone is beyond thrilled for them."

Bilson and Hayden hooked in 2007, and exchanged rings in 2008. However, two years later they called it quits. They reunited again in 2010 and have been going strong since then.

The baby news has come as a pleasant surprise for the couple, as the former O.C star 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. "I've always wanted to be a mom. I have always wanted kids. I can just see this little toddler waddling around the house."

Moreover, Bilson has a rock solid support in Hyden.

"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 spotted at CW Upfronts in a floral printed dress. The former "O.C" star was seen wearing a Mary Katrantzou creation, which worked wonders in hiding her bump.

The actress, who made ripples in the industry with "OC" 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," she told E! about the upcoming season of the show.

"Heart of Dixie" star cast includes Bilson, Jaime King, Cress Williams, Wilson Bethel, Scott Porter, Tim Matheson and Kaitlyn Black. It has been created by Leila Gerstein, and has Bilson in the lead role as Dr. Zoe Hart. Bilson is a cardiologist whose dreams fall apart and she moves to Gulf Coast town of Bluebell, Alabama to work as a general practitioner.

On May 8, 2014, the CW renewed the show for its fourth season
