Carrie Underwood was worried she was going to get kicked off 'American Idol'

Country music superstar Carrie Underwood stopped by The Late Show on Thursday where she reminisced with Stephen Colbert over her life-changing American Idol audition 15 years ago. Growing up in the small town of Checotah, Oklahoma, the Grammy award-winning singer said she had minimal expectations and nothing to lose. “I didn't know what was going to come of it. I saw the auditions on the news happening in other towns, so I thought, why not? Worked out all right,” said Underwood. In response, Colbert joked, “That was the shortest autobiography I've ever read.” Traveling to Hollywood after receiving the American Idol golden ticket was Underwood’s first flying experience, and she was “terrified.” and still is to this day despite all the flying she does. A small-town girl navigating multiple flight connections by herself, during her first time flying, was almost a disaster for the "Idol" season four winner because she missed her connecting flight to LA. Not knowing what to do, Underwood phoned her American Idol contact and begged them not to kick her off the show. But, luckily for Carrie, and all of her fans, she made it to the Idol auditions and the rest is history. Underwood closed out the show with a performance of ‘Low” from her album Cry Pretty.
