Pop singer Ariana Grande stopped by 'Late Night with Jimmy Fallon' Friday night (Sept. 6) for a very special rendition of hip-hop classics and thrifty hits.

Decked out in her signature '50s-style circle skirt and a white top, she sat on top of a piano to sing while Jimmy Fallon played Broadway versions of Jay Z's '99 Problems,' Cypress Hill's 'Insane in the Membrane' and Macklemore & Ryan Lewis' 'Thrift Shop.'

In the funny three minutes, Ariana shows her vocal chops and Jimmy, as usual, brings in the comical visuals wearing a lace-front blond wig.

We dare you not to laugh when he says, "Hey Ariana, let's talk about girl problems."
