Sophia Bush
A stunning former beauty queen and journalism student, Sophia Bush made a name for herself as the seductive vixen Brooke Davis on the long-running teen drama series, "One Tree Hill" (The WB, 2003-12). She sparked a press frenzy with her real-life marriage to "Tree" co-star Chad Michael Murray - and their subsequent divorce only five months later. Although she was replaced as the female lead in "Terminator 3: Rise of the Machines" (2003) by Claire Danes, Bush did earn some big screen success in the horror and teen genres, with the successes "Stay Alive" (2006), "John Tucker Must Die" (2006) and "The Hitcher" (2007). Though often cast as the flirtatious bad girl, Bush's down-to-earth persona and intelligence grounded her on the big and small screens, adding a deeper layer to many of her characters and hinting at a potential which fans believed she would fulfill.
