Sixty family members and friends looked on as the couple -- friends for six years -- said "I Do." The singer's season 9 Idol pal Didi Benami and It's Always Sunny in Philadelphia actor Lance Barber were also in attendance.

Bowersox's 1-year-old son, Tony, served as ring bearer.

"Officially walkersox," the 25-year-old bride Twittered after swapping vows Sunday.

It was a whirlwind romance for the couple, who announced their engagement in September, four months after Bowersox split from her boyfriend the day before the Idol finale.

"It was bad timing," she told Ellen DeGeneres of her May 2010 split. "He's a small town guy, and I don't blame him for anything."
