Newly Single Rachel Bilson Out and About!

Former OC-star Rachel Bilson was seen out and about in Beverly Hills rocking a cute black dress and hiding behind big, dark sunglasses! The star stopped to sign for a gay marriage rights petition and then proceeded to take something out of her bag...I wonder what that could have been? Maybe a pen or a donation of some sort? I guess we'll never know! At least actress Bilson isn't moping at home after the split with her on and off screen beau Hayden Christensen! The pair were engaged for quite some time, but at a recent movie premiere Rachel wasn't wearing her diamond engagement ring! Trouble in paradise! We hope she finds someone else soon! Personally I wouldn't mind seeing her back with OC co-star Adam Brody! Now that was a cute couple!
