Crystal Bowersox is going solo.

The American Idol runner-up and musician husband Brian Walker are splitting up, People reports.

"After two and a half years, we have decided to end our marriage," the pair said in a 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."

They did not have any children together. Bowersox has a 4-year-old son, Tony, from a previous relationship.

In fact, she and her child's father broke up during her impressive run on Idol, which only ended when she lost to Lee DeWyze in the finale. 

"It was a mutual thing," Bowersox revealed at the time. "We're both logical adults. He's a small-town guy—that's fine. I'm a small-town girl, but I want this more than anything. I want this career, this lifestyle, and I didn't think he was up for it. And he didn't think he was up for it."

She and Walker tied the knot in October 2010 after a whirlwind engagement.
