After Ariana Grande stopped by Good Morning America to apologize one more time for #donutgate, she traveled over to 30 Rock to stop by The Tonight Show With Jimmy Fallon. Fallon loves challenging his guests to impressions of your favorite celebs so he enlisted Ariana in a round of "Wheel Of Musical Impressions." First up was Ari singing "Mary Had A Little Lamb" as Britney Spears (which was almost as good as Christina's previous impression of Britney). Then, she went full-Christina Aguilera to belt her rendition of "The Wheels On The Bus" that left the audience astounded. The greatest moment might be when she takes on The Weeknd's "Can't Feel My Face" in her best Celine Dion impersonation with an assist from Jimmy singing as Sting. Watch it all go down above.
