Rachel Bilson is yet another beautiful brunette born to act. It's in her DNA — her father is a writer-director-producer, grandfather a director and her great-grandmother a screenwriter. She worked with dear ol' dad at 6 o the Louie Anderson-starrer The Wrong Guys. After a one-year college try in San Diego, she returned to Hollywood to audition for commercials (She scored one for Subway.) and pilots. After failing to nab a part in Everwood in 1999, she was recommended to Josh Schwartz, who at the time was casting the pivotal teen drama The O.C. He'd found his spoiled and stylish Summer Roberts. The series debuted in 2003 and she immediately started dating costar Adam Brody with whom she shared a pit bull terrier named Penny Lane. She parlayed the TV buzz into movie gigs including 2005's The Last Kiss with Zach Braff and 2007's Jumper. At the end of 2006, Brody and Bilson called it quits and she moved on with her Jumper costar Hayden Christensen. The sci-fi stunners got engaged over the 2008 holidays, separated before a ceremony happened in 2010 and then reunited a few months after announcing the split. In 2011, the stylish starlet returned to the small screen with Hart Of Dixie. She plays the title character, a Manhattan medical school grad who moves to the small town South after finding out her secret biological father left her a practice there.
