24-year-old Chad Michael Murray got engaged to his 18-year-old One Tree Hill costar Kenzie Dalton.
The relationship was his first since his split from Sophia Bush (who he cheated on with House of Wax costar Paris Hilton).
Despite the fact that he was still legally married to Sophia, he started dating Kenzie in December 2005 - when she was 17 - and proposed to her less than a month after her 18th birthday.
The two split in 2013 amidst reports he was cheating on her with Nicky Whelan.
Fun Fact: He was banned from her senior prom. The school had a policy that no one over 20 was allowed to attend - so Chad threw the after party for Kenzie and her friends.
