Kelly Clarkson joined Jimmy Fallon last night for a four-minute supercut of some of the greatest duets of all time. Similar to what Fallon did with Timberlake with rap, Clarkson and the host adorably plowed through a playlist of hits, kicking it off hand holding and skipping to Sonny and Cher's "I Got You Babe" and wrapping it all up with Lionel Richie and Diana Ross' "Endless Love."

Watch below (and check out the tracklist below as well)!
