Jimmy Fallon, Selena Gomez sing 'Mario Kart Love Song' - watch
The pair sang an ode to Nintendo on Late Night on Tuesday (March 21) for a spirited cover of Sam Hart's viral hit 'Mario Kart Love Song'.
Fallon and Gomez even donned the video game plumber's famous moustache as they sang about the love between a beautiful princess and a less-than-handsome toad.
The Late Night presenter has become famous for his musical parodies, having previously shared the stage with Carrie Underwood, Andy Samberg and Adam Sandler, Bruce Springsteen and others.
Gomez has been on the promotional circuit in advance of the wide release of her new film Spring Breakers.
The 'A Year Without Rain' singer made headlines for an appearance on The Late Show with David Letterman this week for joking about making ex-boyfriend Justin Bieber cry.
