Sophia Bush (born July 8, 1982) is an actress who has most recently appeared in the WB Television show One Tree Hill as Brooke Davis.

Born and raised in Pasadena, California, Sophia attended Westridge School for Girls (Pasadena) and the University of Southern California and was a member of the Kappa Kappa Gamma sorority, where she served as Social Chair. She attended USC for three years before getting the role of "Brooke Davis" on "One Tree Hill" (2003). In 2000 she was the Tournament of Roses Parade Queen.

An only child, her father is Charles William Bush, one of the top advertising and celebrity photographers working in the United States today, while her mother, Maureen Bush, is a photography studio manager.

Bush made her first big screen appearance in the comedy Van Wilder. Since then, she has made appearances in several television shows including Nip/Tuck, Sabrina, the Teenage Witch, and Punk'd after being tricked by her friend Brittany Snow. She was cast as Kate Brewster in Terminator 3: Rise of the Machines but was replaced by Claire Danes as the director thought she was too young.

On April 16, 2005 she married her One Tree Hill co-star Chad Michael Murray, but the couple announced their separation on September 26 after only five months of marriage.

Bush spoke of the breakup in an upcoming issue of the teen magazine CosmoGirl, stating "I can't say there are no hard feelings... I feel hurt, humiliated and broken hearted." She does not go into details about the break-up, but states that she is shocked at the accuracy of some of the reports about the reasons for the split (reports which include allegations that Chad Michael Murray cheated on her with Paris Hilton).
