Rachel Bilson: Bardot Babe

Rachel Bilson is led through the paparazzi by a gal pal Jill Stonerock as they leave Bardot lounge in Hollywood on Thursday night (August 6).

The 27-year-old actress was there to celebrate pal Josh Schwartz‘s 33rd birthday. In the pictures below, Josh is wearing the blue/red plaid shirt and is holding his wife Jill‘s hand.

Josh and Jill were married in September 2008 and had Rachel serve as the the maid of honor at the wedding.

Who else was there for Josh‘s birthday bash? Gossip Girl‘s Chace Crawford and Melrose Place‘s Ashlee Simpson. (Josh created Gossip Girl and The O.C., which helped launch Rachel‘s career.)
