Kelly Clarkson is the queen of covers [1], and her latest "Kellyoke" song [2] did not disappoint. On Friday, the 37-year-old singer opened up The Kelly Clarkson Show [3] by singing Katy Perry [4]'s "Roar," and of course, she nailed it. How is it that every song Clarkson covers sounds like an entirely new one? You know, I wouldn't mind an album of all of Clarkson's covers, just saying. Check out her amazing performance above!
