Kelly Clarkson's mega hit "Since You Been Gone" came out all the way back in 2004, but it's taken all these years later for the people over at VH1 to give the song their Pop Up Video treatment. You'll learn a lot about Kelly while watching it, including the fact that she never wears underwear! Um, I think I could've gone the rest of my life not knowing that, but I digress! Lol, check out the Pop Up Vid below...
