Rachel Bilson Has an 'O.C.' Reunion with Autumn Reeser!

Rachel Bilson steps out in a white dress while grabbing lunch with her mom Janice at Stamp on Tuesday afternoon (September 30) in Los Feliz, Calif.

The 33-year-old actress is pregnant with her first child and it looks like her due date is getting closer and closer!

Rachel is wrapping up work on the fourth season of her CW series Hart of Dixie, which will premiere next year. She just had a little reunion with her The OC co-star Autumn Reeser for the finale episode.

“Love this girl, such a pleasure to work w/ her again!! A mini #OC reunion on the finale ep of @CWHartofDixie…” Autumn wrote on WhoSay. See the pic below!
