If John Mellencamp had his way, daughter Teddi Mellencamp would be closer to home during her stage 4 cancer battle. "I'm going to go out and see her [in Los Angeles]," John, 74, shared on the Friday, January 16, episode of the Today show. "I've tried to talk her into moving back home. I said, 'Move back to Indiana, bring the kids and just come back and live in Indiana,' but she won't do it." Teddi, 44 - who shares Slate, 12, Cruz, 11, and Dove, 5, with estranged husband Edwin Arroyave - was first diagnosed with stage 2 melanoma in October 2022.
