Mellencamp has been self-deprecating about his personality before. During an appearance on Howard Stern's SiriusXM show last March -- prior to his reunion with Ryan -- he noted that she wasn't exactly friendly toward him at the time and put the blame on himself.
"Oh, women hate me," he said. "I loved Meg Ryan. She hates me to death."
"I think it’s because I’m a child. I throw fits, I gripe, I complain," he continued. "I’m moody. Every bad thing that a fella can be, that’s me.”
Clearly, the two were able to work out their issues, and last month, the 57-year-old actress looked incredible while sporting her engagement ring at the Friar's Club Entertainment Icon Award event in New York City.
