Rachel Bilson is a Gelson's Girl

Rachel Bilson visits a friend’s house after a brief shopping trip at her local Gelson’s supermarket in the Los Feliz neighborhood of Los Angeles on Thursday afternoon (August 6).

The 27-year-old former O.C. actress seemed to be celebrating someone’s birthday as a mystery female was seen carrying in some birthday balloons. Last week, Rachel celebrated the birthday of her dad, director/producer Danny Bilson. Maybe it’s another celebration for him??
