To any anybody who went to high school or University from 2003-2007, you will be quick to point out that Bilson is most well known to the world as Summer Roberts, from the smash TV show “The OC”.
While Summer Roberts became a staple on the show, the character was only intended to be used for a few episodes during the first season. After seeing how popular the character was, the writers of The OC quickly opted to make her one of the main characters. Sure enough as fate would have it, Rachel Bilson would go on to win numerous Teen Choice Awards for her role as Summer Roberts and helped The O.C. attain cult status during the mid part of the decade.
