It has been ten years since American Idol crowned Carrie Underwood the winner of the vocal reality competition. Since her triumph, Underwood has climbed the ranks as one of the most popular women in country music, as well as selling-out stadiums around the world while topping the charts with album after album.

All of this has made her one of the most successful Idol winners.

People reported that Underwood posted an image of her Idol win on Instagram with the caption, "So hard to believe it's been 10 years! I'm forever grateful to American Idol for changing my life! #blessed."

Underwood beat out Bo Bice to take home the title of Idol during season four. She released "Inside Your Heaven" and "Jesus Take The Wheel" following her win, both of which shot up the Billboard charts and helped to launch her into musical superstardom.

Idol is heading into it's final season after it was announced that Fox would be canceling the show. Last season's finale hit a series low for ratings, Deadline added.
