Ariana Grande stopped by The Tonight Show Starring Jimmy Fallon on Tuesday night and delivered the most epic impression of Britney Spears and Christina Aguilera.

During Fallon’s segment, Wheel Of Musical Impressions, Grande first had to belt out “Mary Had A Little Lamb” in her best Britney voice. Ariana started off with a little rasp in her voice before hitting her first note. And all we can say is … spot on.

Fallon followed up with a stellar impression of Aaron Neville singing “Cheerleader” and then, it was Grande’s turn again. And she absolutely killed it. The singer took on “The Wheels On The Bus” and her best Christina vocals and even through in a few classic Aguilera ad-libs. Simply comical.

And the singer’s last challenge, Celine Dion to The Weekend’s “Can’t Feel My Face.”
