Idol's Crystal Bowersox Split with Boyfriend Day of Final Performance

Crystal Bowersox's boyfriend Tony supported her every step of the way during her journey on American Idol, so it was a telling moment when he wasn't in the audience during last night's finale. After the show, Crystal spoke to OK! about his absence.

"He's driving somewhere," she told OK!.

That answer made even more sense this morning as Crystal revealed to Ryan Seacrest on his radio show that she and her boyfriend called it quits the morning of the final performances.

"Big Tony... he went home. He wasn't cool with the lifestyle," she explained to Ryan and Kara DioGuardi. "I didn't break up with him... it was a mutual thing."

As they spoke, Tony was on his way home to Toledo, Ohio.

"It's cool though, we're both logical, grown adults," Crystal added. "He's a small town guy and that's fine, 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."

Ultimately, Crystal lost out to Lee DeWyze, but she was proud of her performance.

"I was a little sad that he did it on performance day, but then again it set that fire to my belly."
