Rachel Bilson wears a colorful skirt while visiting her friend’s house in Los Angeles on Thursday (October 28).

The 29-year-old former O.C. actress stopped by a Santa Monica movie set on Wednesday.

Miss RB on the small screen? She’ll be starring in a rom-com with O.C. creator/exclusive producer Josh Schwartz at the helm! Rachel will play a character who helps dead spirits with the spirits helping her as well!

FYI: Rachel is wearing the Kate tank from Market
