They had a whirlwind courtship and an engagement lasting only weeks, but Crystal Bowersox and Brian Walker were hardly strangers in love.
Longtime friends before things turned romantic in recent months, the American Idol runner-up was married to musician Walker in Chicago on Sunday, her rep tells PEOPLE exclusively.
“Our lives have never made more sense than they do right now, Bowersox tells 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, wore an Earth-friendly hemp and cotton gown from Vermont designer Tara Lynn that features macramé, seashell and bead detailing and was created in the designer s solar-powered studio.
Their rings were designed by Walker and crafted by Chicago s Traci Coughlin and Steve Quick Jewelers. The ceremony was held at the Uncommon Ground Café, where they met during Open Mic Night six years ago.
Among the 60 friends and family in attendance were Bowersox’s son Tony, 1 1/2, from a previous relationship, who served as ring bearer and wore a suit by LinenKids; Season 9 Idol contestant Didi Benami; and It s Always Sunny in Philadelphia actor Lance Barber. The ceremony was led by the right reverend Michael Teach from Chicago Acoustic Underground.
The couple, who announced their engagement in September, planned to celebrate with a reception featuring a laughing Buddha cake from Bleeding Heart Bakery, a local organic and sustainable business, and performances from the groom and several musician pals.
Bowersox next returns to the studio, where she’s been recording her debut album.
