The couple, who were longtime friends before becoming romantic in recent months, tied the knot Sunday in a Chicago club where they first met at an open-mic night six years ago. Bowersox's 1-year-old son, Tony, from a previous relationship served as ring bearer.

Among the 60 friends and family members in attendance were fellow Season 9 Idol contestant Didi Benami and It's Always Sunny in Philadelphia actor Lance Barber.

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

Bowersox, 25, split from her then-boyfriend, Tony Kusian, hours before the Idol finale performance in May. She and Walker announced their engagement in September.

An e-mail to Bowersox's rep was not immediately returned.
