If you weren't paying close attention, you might have thought Britney Spears, Christina Aguilera and Celine Dion all made appearances on The Tonight Show Tuesday.

But in reality, it was actually just Ariana Grande doing her best imitations of the pop divas for Jimmy Fallon's "Wheel of Musical Impressions."

Grande offered up renditions of "Mary Had a Little Lamb" and "The Wheels on the Bus" in the styles of Spears and Aguilera, respectively, while Fallon did his best Aaron Neville. The best moment of the video, however, is when they duet - as Celine Dion and Sting - on The Weeknd's "Can't Feel My Face."
