Rachel Bilson is ready to get her first pregnancy rolling! The Hart of Dixie star hit up Five Guys Burgers and Fries in Studio City, Los Angeles on Monday, June 30 with longtime boyfriend Hayden Christensen

The mommy-to-be, 32, went casual in a baseball cap and cut-off T-shirt that read “Lets Roll.” Her growing baby bump was barely visible in the loose-fitted clothes. Christensen, 33, stood close by, opening the door to the fast food spot to let his girlfriend out. 

In mid-June the expectant parents returned to California following an extended babymoon in Barbados, where Bilson’s bump was much more visible in a series of bikinis.

Us Weekly exclusively broke the news of the O.C. alum’s first pregnancy in May. 

"They've both talked about this for awhile and are so excited," a Bilson insider told Us at the time. "Everyone is beyond thrilled for them."
