'American Idol': 8 stars surprisingly rejected by the competition series
{{#rendered}} {{/rendered}}"American Idol" has launched the careers of some of today's biggest stars in music.
Kelly Clarkson and Carrie Underwood are the show's most notable winners, but even the likes of Jennifer Hudson and Chris Daughtry, who didn't come in first place during their time on the series, made it big after appearing on the show.
While the show has churned out superstars for 17 seasons now, there have been a few who slipped through the cracks over the years.

As popular as her song "Bubbly" became, it's hard to imagine "American Idol" turning Colbie Caillat away, but they did -- twice.
The songstress, 34, was rejected both times she auditioned, performing her hit pop tune during her second go-round (per the Daily News).
