Rachel Bilson stepped out of a Thai restaurant in LA yesterday with her boyfriend Hayden Christensen following closely behind. The on-again couple met for a low-key lunch during a break from Rachel's busy filming schedule. She's in the middle of production on her CW series, Hart of Dixie, which was just picked up for a full season. Rachel recently promoted the drama during a trip to NYC, where she stopped by Late Night With Jimmy Fallon and shared about her experience filming on location. The South may be a different scene than the West Coast, but Rachel Bilson's cute style is still intact on the small screen hit.
