Supermodel Christie Brinkley and singer John Mellencamp have split after a year of dating, a rep for the pair tells PEOPLE exclusively.
“Both the mileage between their homes and their heavy career demands interfered with their ability to maintain the relationship,” a rep for both Brinkley and Mellencamp tells PEOPLE. “They vowed to remain best of friends.”
Brinkley, 62, has been busy promoting her new line of Prosecco, Bellissima, this summer. Mellencamp, 64, has been touring this spring and was set to resume his American tour this summer.
