Besides providing an easy-to-remember anniversary, 10-10-10 turned out to be a harmonious date for singer Crystal Bowersox

Joining the ten-tastic day's other high-profile newlyweds, the American Idol runner-up wed musician Brian Walker Sunday, E! News has confirmed. 

"Officially mamasox!!!" tweeted Bowersox, who reportedly strolled down the aisle in a hemp and cotton gown by designer Tara Lynn. "I mean walkersox!!! Hahaha that's hilarious. :)"

The Chicago ceremony, attended by about 60 guests, was held at the same club where the couple met six years ago, according to People. Fellow Idol contestant Didi Benami was among guests in attendance, and Bowersox's son, Tony, from a previous relationship, served as ringbearer.

The newlyweds announced their engagement just last month.
