Melanie and Don started dating when the actress was just 14 years old. They met on the set of "The Harrad Experiment," in which Don, then 22, had a small role alongside Melanie's mom, actress Tippi Hedren. Four years later, in January 1976, the couple wed in Las Vegas once Melanie turned 18. But their marriage ended after just six months -- at least until the couple reunited and wed for a second time in 1989. Their second marriage lasted until 1996.
