Kelly Clarkson has apparently been saying she's had trouble finding duet partners (Uh, what do you call "From Justin to Kelly," young lady?), so Jimmy Fallon decided to help her out. He took advantage of Clarkson's appearance on "The Tonight Show" to sing a whole bunch of duets with her, starting, naturally with the Sonny and Cher classic "I got you babe," but also including a more modern number with the Pink/Nate Ruess song, "Just Give Me a Reason." Watch the video below to see if they got to your favorite duet. And don't worry, the '80s are heavily represented, Jimmy incorporates a costume change and a stone cold classic Paula Abdul song makes it in.
