Jason Aldean has filed for divorce.

The country music star filed the complaint for divorce against his wife Jessica on Friday afternoon in Williamson County, Tenn., citing irreconcilable differences.

Aldean's publicist confirmed last week the couple had separated after media reports surfaced. The filing comes six months after Aldean was photographed while appearing to kiss former "American Idol" contestant Brittany Kerr in a Los Angeles bar. Aldean later apologized for acting inappropriately.

The couple has been married since August 2001. They have two young daughters together, Keeley and Kendyl.
