Ariana Grande's killer impression of Celine Dion

Christina Aguilera did a great impression of Britney Spears recently, but Ariana Grande's one of Celine Dion is even better.

The singer made her first speaking appearance as a guest on The Tonight Show with Jimmy Fallon this week.

Seeing this rare opportunity with the pint-sized star, Jimmy, 40, was quick to take advantage of her skills.

Watch the 21-year-old's pitch-perfect rendition of Celine's 1992 duet 'Beauty and the Beast' in the video above.
