Selena Gomez and Jimmy Fallon Sing "Mario Kart Love Song"

Selena Gomez just got even cuter! Is that even possible?

On Tuesday, the 20-year-old hit up the "Late Night With Jimmy Fallon" show where she and the hilarious talk show host performed one adorable duet of Sam Hart's "Mario Kart Love Song."

Fallon sported a red Mario hat and a mustache and Gomez wore a Princess Peach crown (in addition to a curly mustache) for the video game-inspired tune.

We know the former Disney star can sing, but check out Jimmy -- he has a pretty good voice and he's not too shabby on the guitar.

How do you think they did? Check out the video above and sound off below!
