Just when we thought A Great Big World and Christina Aguilera [1]'s "Say Something" couldn't make us cry more, Kelly Clarkson [2] went ahead and proved us wrong. During The Kelly Clarkson Show [3] on Thursday, the singer gave a stunning rendition of the emotional ballad for her latest rendition of "Kellyoke [4]." We all know Clarkson has a powerhouse voice [5], but there's something otherworldly about her high notes. Our only critique about the cover is that it isn't longer! Seriously, we need a full version of this track . . . or at least a duet between Clarkson and Aguilera. Imagine how powerful that would be! Prepare to be amazed by Clarkson's stunning cover above.
