Jason Aldean, the biggest selling American country star, has filed for divorce from his wife of 11 years, Jessica Aldean. Jason was snapped kissing American Idol contestant Brittany Kerr on the Sunset Strip last year, though it appeared that he and his wife had worked through their problems.

The pair appeared together on the red-carpet in November, though it appears the incident with Kerr has damaged the marriage irreparably. "This is a really tough time for my entire family," Aldean said in a statement on Monday afternoon, "Jessica and I have been together since we were teenagers. We've been through a lot of ups and downs over the years as we grew up together as a couple. She will always be important to me because she is themother  of my children, and I know that we will both always make our daughters our (hash)1 priority."

The 36-year-old singer filed divorce papers in Tennessee on April 26 - the same day that he announced he and Jessica had separated. The couple have two children together, daughters Keeley and Kendyl. They met at the Windsor Academy high-school in Georgia and married on August 4, 2001.

Aldean recently won the Academy of Country Music's male vocalist of the year award. He is the biggest selling male country star in the U.S with an estimated wealth of $15 million.
