The couple parted ways in August (14) after more than three years together, but it appears the stars are now keen to give their relationship another chance.
Mellencamp, who lives in Indiana, has been open about his feelings for the When Harry Met Sally star in recent weeks and admitted last month (Sep14) he would not rule out rekindling the romance.
He told U.S. shock jock Howard Stern, "Meg is an angel. She was just an angel sent to me at the right time. We tried to have a relationship for three years - long distance. We'll see what happens."
Mellencamp, 63, previously revealed to Rolling Stone that he had no intention of moving to the Big Apple to be closer to Ryan, admitting, "I'm too sensitive to live there (in New York). I can't see poor people. I can't see the suffering. I can't see the trash on the streets. I'm not leaving Indiana. I'm going to die here."
