Crystal Bowersox has confirmed she married musician Brian Walker in a Chicago nightclub.

The "American Idol" runnerup and Walker had been friends for years, but only recently started dating, the singer's publicist told

The couple wed Sunday before about 60 family members and friends in the club where they met at an open mic night six years ago.

"Our lives have never made more sense than they do right now," Bowersox told

"I can't believe how incredibly lucky we are to have found so much laughter, love, and light within each other. We're one happy WalkerSox family."
