Kris Allen Recalls Dumping His Now-Wife On 'When I Was 17'

'She was awesome, but I was a jerk,' he says on the show, which airs Saturday at 11 a.m. on MTV.

Listen up, all you heartbroken souls! Just because you broke up with your boyfriend or girlfriend doesn't mean you won't someday get back together. And get married. And see your spouse go on to win "American Idol."

That's the takeaway from Kris Allen's romance with his high school sweetheart, as the singer explains in the upcoming episode of "When I Was 17," airing Saturday at 11 a.m. on MTV. "When I was 17, I broke up with my future wife," he admitted.

Arkansas native Allen and future wife Katy had been dating for about a year when their final year of high school rolled around and Kris decided he needed space to rock out like a true senior.

"She was awesome, but I was a jerk. I was like, 'Aw, it's my senior year. I've got to be free like a bird. Can't have this ball and chain on me,' " he explained.

He probably should've realized it before, but Allen was not exactly the type of guy who could move on from one girl and embrace countless others. "I had no game with the ladies, but with her, it was really easy to go up and talk to her, and everything just always clicked," he said. "Everyone was like, 'Oh, they're going to end up together forever.' "

Nonetheless, they split, first for a two-week break and then for what both thought would be a permanent separation. "She had a hard time dealing with it," Allen said. "Actually, our lockers were right next to each other, so that was pretty tough."

But eventually they got back together and ended up getting hitched shortly before Allen debuted on the eighth season of "American Idol," which he went on to win. But the guy still feels bad about how he treated his sweetheart back in the day.

"I was more worried about my senior year and having fun than being a boyfriend," he said. "I'm sorry, Katy. I was being a jerk!"

"When I Was 17" — this week featuring Allen, Kourtney Kardashian and Travie McCoy — airs Saturday at 11 a.m. on MTV.
