Chad Michael Murray

Recurring parts on Gilmore Girls and Dawson's Creek earned this former model a bevy of young fans. But it wasn't until Murray took on the role of a brooding intellectual on the prime-time teen soap One Tree Hill that he became a star. On the big screen, the blond heartthrob played Prince Charming to teen queens Lindsay Lohan (Freaky Friday) and Hilary Duff (A Cinderella Story) but off screen he courted and married his One Tree Hill love interest Sophia Bush in April 2005. Although the union didn't even last the year, the estranged spouses continued their on-screen romance as they filed real-life divorce papers. To make matters on set even more dramatic, Murray got engaged to 18-year-old One Tree Hill extra Kenzie Dalton in April 2006, many months before his divorce became finalized.
