Jepsen, who was a “Late Night” guest Thursday (June 7), handles lead vocals on Fallon’s rendition. He sings backup while The Roots play various kids’ classroom instruments like a toy xylophone, bongos and a kazoo.
Fallon and the Roots join the ranks of celebs like Justin Bieber and Katy Perry who have made their own videos for the song.
Check out Fallon’s video below.
