Carrie Underwood was left hiding behind her hands as she was forced to relive a "haunting" moment during her American Idol debut.

Carrie Underwood is a Hollywood star — as in, a celebrity — who still cringes when she thinks of a gaffe she made on American Idol two decades ago. In a recent Instagram vide o in the reality show’s #IdolToIcon series, Underwood rewatched a clip from her Idol debut in 2005, when she won the competition’s fourth season.

Country singer Carrie Underwood took on a new role when she replaced Katy Perry as judge for the 23rd season of American Idol. It was the perfect fit as Carrie has plenty of experience with reality TV singing competition series — she won it once before.
