Jason Aldean and his wife, Jessica Ussery have separated, less than a year after Aldean was caught kissing Brittany Kerr, a Charlotte Bobcats dancer and former American Idol contestant.

Ussery didn't attend the ACM Awards earlier this month.  Sources say the split could have happened in January.

US Weekly says the couple were having problems.and they have asked for privacy for their two daughters Keeley and Kendyl. The magazine says the couple were having problems even before the kiss with Kerr.

“The truth is that I screwed up,” Aldean said in a statement after the kiss. “I had too much to drink, let the party get out of hand and acted inappropriately at a bar … I ultimately ended up embarrassing my family and myself.”
