VIDEO : Ariana Grande Nails Impersonations of Britney Spears, Christina Aguilera & Celine Dion

Ariana Grande has proven to be a master impersonator. The last time she was on The Tonight Show Starring Jimmy Fallon, Grande did an amazing impersonation of Celine Dion. This time, she showed off her skills again, playing "wheel of musical impressions" with Fallon. Grande had to sing "Mary Had a Little Lamb" as Britney Spears, "The Wheels on the Bus" as Christina Aguilera and "Can't Feel My Face," as Dion -- and she killed it Fallon was no slouch either. He sang "Cheerleader" as Aaron Neville, "Can't Feel My Face" as Sting, then joined Grande for a duet on the final song.
