The country singer filed the papers in Tennessee on April 26, citing irreconcilable differences. Aldean and Ussery, who were high school sweethearts, have two children together.
News of their split comes seven months after pictures of Aldean kissing American Idol Season 11 contestant Brittany Kerr surfaced on TMZ. "The truth is that I screwed up. I had too much to drink, let the party get out of hand and acted inappropriately at a bar," Aldean wrote on his Facebook page at the time. "I ultimately ended up embarrassing my family and myself. I'm not perfect, and I'm sorry for disappointing you guys."
Earlier this month, Aldean announced that he and his wife had separated, with his rep stating that they were "having problems."
