Rachel Bilson Shows Off Her Engagement Ring

Rachel Bilson coyly showed off her engagement ring to paps yesterday afternoon while out on a grocery shopping run in Los Angeles.
The former O.C. star has been keeping her engagement to actor Hayden Christensen on the down-low for a few months now, but after a “close friend” spilled the dirt a few days ago, Bilson has no reason to keep it a secret anymore.
Nice rock!
