Who knew that a girl who almost lost a singing concert to Justin Guarini would go on to be one of the best singers of our generation?

Kelly Clarkson, the original American Idol and current Billboard dominator, has been making waves with the covers she has been turning out on her new tour. During the sound check of each show, Clarkson has been asking fans what they want to hear her sing, and chooses one of those songs to do live during her show.

Last night someone finally requested a little Florence + The Machine, and Clarkson KILLED it!

Check out the video of Kelly covering Shake It Off below and let us know what you think!
