Rachel Bilson's Flea Market Frenzy

Rachel Bilson and a female friend rummage through clothing racks and vintage items at the Flea Market in West Hollywood on Sunday.

The former O.C. actress has said, “I love to shop. I love going to the thrift store and flea markets and digging through things and finding little pieces. I love vintage!”

Rachel, 26, took along her pet pooch, Thurman Murmen, as she strolled around town.
