Cue Clarkson, who popped out from behind the curtains. "Did somebody say duet?" she asked, patting her hair.

No more introduction necessary!

Fallon joined her on stage and the dynamic duo blazed their way through a collection of memorable duets, doing an awesome job whether or not they were imitating the original singers.

The massive medley included tunes by Sonny and Cher (1965's "I Got You Babe"); Dolly Parton and Kenny Rogers (1983's "Islands in the Stream") and Elton John and Kiki Dee (1976's "Don't Go Breaking My Heart").

Two, two nice! Jimmy Fallon and Kelly Clarkson.
