Stayed Together On-Set: Chad clearly holds a flame for his female co-stars. After falling for Sophia on the set of One Tree Hill, he admitted to being unfaithful to her — many believe with his 2005 House of Wax co-star Paris Hilton. After the split, the pair continued to work together for three more years. In December 2005, Chad began dating former OTH extra Kenzie Dalton, before he and Sophia officially filed for divorce. Chad and Kenzie are currently engaged.
