Jimmy Fallon and Kelly Clarkson are match made in duet heaven. Singing great songs from "I got you Babe" to "Endless Love".

Kelly Clarkson came on The Tonight Show to promote her latest album "Piece by Piece" that came out today and decided to partner up with Jimmy for a bit called "History of Duets". They covered 11 of some of the greatest duets of all time in under five minutes!
