Thursday,  Nov. 17 Kelly Clarkson is going “Unplugged” for VH1, but the station has released this sneak peek video and guess what? It’s one of our favorite Idols covering another of our favorite Idols!

Clarkson covers “I Know You Won’t,” which was featured on Carrie Underwood‘s 2007 album “Carnival Ride.” We’ve embedded Carrie’s album version below. We honestly don’t know which one we like better. We prefer the stripped down, acoustic arrangement of the song that Kelly performs, but we have no doubt Carrie could perform it that way too.

Either way – who’s in for a Kelly-Carrie duet? Make it happy, ladies! You know the fans would love it. Which version of “I Know You Won’t” do you prefer?
