Ariana Grande is a 22-year old singer who has an uncanny resemblance to a living Bratz doll. That's not the point of this post, though. What we're focusing on today is that she's pretty good at doing impressions of the singers that came before her. 

Whether it's impersonating Britney Spears singing "Mary Had a Little Lamb" or Celine Dion singing "Can't Feel My Face," Ariana's got some vocal chops.
