2013's Biggest Splits
Jason Aldean and Jessica Ulssey
Seven months after the country singer was caught kissing American Idol alum Brittany Kerr, Aldean filed for divorce from his wife of nearly 12 years. "This is a really tough time for my entire family," Aldean told Us Weekly in a statement at the time. "Jessica and I have been together since we were teenagers . . . 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."
