Christie Brinkley and John Mellencamp Call It Quits After a Year Together 

The former supermodel and her singer boyfriend have decided to part ways.

In what is shaping up to be the Summer of Breakups, Sports Illustrated stunner Christie Brinkley and John Mellencamp have announced that they are ending things after just a year of dating.

“Both the mileage between their homes and their heavy career demands interfered with their ability to maintain the relationship,” a rep for the couple told People. But the two have “vowed to remain best of friends.”

This summer, Brinkley, 62, is hard at work promoting Prosecco, Bellissima, while Mellencamp, 64, is preparing to tour the U.S. this fall.

The two bonded over their kids and being roughly the same age, a rarity in the youth-centric world of show business.

“I know guys that go out with girls that are so, so young. They’ll throw some reference out, and they’re like, ‘What’s that?'” Brinkley told People in 2015. “When it comes to relationships, there is something nice about just being the same age.”
