Rachel Bilson
Rachel Sarah Bilson (born August 25, 1981) is an American actress. Born to a Californian show-business family, Bilson made her television debut in 2003, and then landed the role of Summer Roberts on the prime-time drama series The O.C. If we had a list of “Cars Most Owned by Celebs” Prius would probably be number one. Here we see another Hollywood starlet driving one.
