Another one bites the dust. Country star Jason Aldean was caught kissing American Idol alum Brittany Kerr while married to his wife of 11 years Jessica Ussery in 2012. Seven months later, the singer filed for divorce. "This is a really tough time for my entire family," Aldean told Us in a statement. "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 No. 1 priority."
