Jason Aldean has filed for divorce from Jessica Ussery.

The 36-year-old country music singer announced on Monday (29.04.13) he will be divorcing his childhood sweet of 12 years, citing irreconcilable differences, after their relationship hit the rocks when he was caught smooching with 'American Idol' star Brittany Kerr last September.

Speaking to People magazine, Aldean said: ''This is a really tough time for my entire family. 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 the mother of my children, and I know that we will both always make our daughters our number one priority.''

The 'Don't You Wanna Stay' musician - who has daughters, Keeley, nine and Kendyl, five, with Jessica - hit the press after sources suggested the couple had actually split back in January and Aldean's rep confirmed the couple were going through a turbulent phase.

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