Jimmy Fallon + Ariana Grande Sing Broadway Renditions of Rap Songs [VIDEO]

As if you didn't have enough reasons to love Ariana Grande, she also has a pretty good sense of humor behind those powerhouse pipes!

The 'Sam + Cat' starlet and 'Yours Truly' singer joined Jimmy Fallon for a silly duet in which they belted out Broadway renditions of classic (and one newly classic) rap joints.

Fallon, sporting a long, stick-straight blond wig, sat at a piano, upon which Grande was perched. The pair began with Jay-Z's '99 Problems,' with Grande crooning, "I got 99 problems but a b---- ain't one." Next up? Cypress Hill's 'Insane in the Membrane.'

The duo closed with a cover of Macklemore's 'Thrift Shop,' the highlight of which was Grande's climactic, "This is f---ing awesome." Tune in above to take it all in!
