The separation between Aldean and Jessica Ussery, which happened in January comes seven months after the Georgian was photographed kissing a former American Idol contestant Brittany Kerr.
"There were obvious problems before the bar kiss, but he finally left earlier this year," a source told US Weekly.
"I can confirm that Jason and his wife are having problems, but there is nothing more to share at this time," the rep said to US Weekly. "It's a private family matter, and we hope everyone will respect that he would like to keep it that way."
Aldean and Ussery were high school sweethearts. The two have two young daughters, Keeley and Kendyl.
The story quoted Aldean's comments on a CBS This Morning show, "It hasn't always been roses," Aldean admitted of his 11-year marriage to Ussery, with whom he has two young daughters, Keeley and Kendyl. "We've been together for a long time and through a lot of things together. Those are things that most people get to deal with in private, but we didn't have the luxury of doing that."
Aldean is currently on tour.
