American Idol runner-up Crystal Bowersox and her husband, musician Brian Walker, are calling it quits.
"After two and a half years, we have decided to end our marriage," the couple tells PEOPLE in an exclusive statement. "The friendship and love which brought us together remains strong, and we will continue to support each other in our careers and personal lives. We are hopeful that people will be respectful of our privacy as we face this emotional and challenging time for our family." After a whirlwind courtship and an engagement that only lasted weeks, the couple tied the knot in front of 60 friends and family members in Chicago in 2010.While the couple had no children, Bowersox, 27, has a 4-year-old son, Tony, from a previous relationship.
