Season-nine "American Idol" runner-up Crystal Bowersox is heading down the aisle. The singer's rep confirmed to People that she's set to swap vows with her musician beau Brian Walker in October.

The impending nuptials come just months after [article id="1640211"]Bowersox broke up with her longtime boyfriend Tony Kusian[/article] in the hours before her final "American Idol" performance. The singer explained that her bourgeoning fame wedged the couple apart. Both agreed that Kusian, who helped raise her toddler son, would prefer a low-key lifestyle.

"He's a small-town guy and that's fine," she told "Idol" host Ryan Seacrest on his KIIS-FM radio program. "I'm a small-town girl, but I want this. I want this more than anything -- this career, this lifestyle. I didn't think he was up for it. He didn't think he was up for it."

In addition to her upcoming wedding, [article id="1640281"]Bowersox has been working on her major-label debut[/article] on 19 Recordings Limited and Jive. The earthy singer inked a contract within a day of the season-nine "Idol" finale but she has recently voiced her issues with her mainstream deal.

"Just frustrated with the politics of the industry. Not just jive just dissapointing how the industry has changed," Bowersox tweeted on Thursday. "Every1s hands are tied."

However, she didn't appear to let the music industry politics get her down, later adding, "regardless, im having the time of my life," before revealing she was recording "Farmer's Daughter."

"Thanks for all of the support, guys," Bowersox wrote to her Twitter followers. "I have more freedom than most signed artists, so imma stop complaining. I love what I do. I am blessed."

Leave your well-wishes for the couple!
