Country singer Jason Aldean has officially filled out paperwork to divorce his wife of 12 years, Jessica Ussery, following an announcement last week that the duo had separated.

According to PEOPLE, Aldean and his high school sweetheart have called it quits, citing "irreconcilable differences" in divorce paperwork filed on April 26.

"I can confirm that Jason and his wife are having problems, but there is nothing more to share with the press at this time," his rep said last week. "It’s a private family matter, and we hope everyone will respect that he would like to keep it that way.”

The divorce comes on the heels of a cheating scandal last September, when Aldean was photographed kissing former 'American Idol' contestant Brittany Kerr at a Hollywood bar.

Aldean issued a public apology at the time, but a source for Us Weekly says he and Jessica (who have two young daughters together) have been separated since January.
