'American Idol' Season 9 runner-up Crystal Bowersox and her husband are divorcing.

"After two and a half years, we have decided to end our marriage," the couple says in a statement to People magazine on Monday (May 6). "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."

Bowersox and her soon-to-be-ex-husband, musician Brian Walker, married in 2010 after a whirlwind courtship and a very brief engagement. They have no children. Bowersox has a four-year-old son, Tony, from a previous relationship.

The 27-year-old singer released an album titled 'Farmer's Daughter;' in 2010. She is slated to star in 'Always ... Patsy Cline' on Broadway this summer.
