Ariana Grande nailed impressions of Britney Spears and Christina Aguilera Tuesday during a visit to "The Tonight Show Starring Jimmy Fallon."

The 22-year-old pop star played Fallon's Wheel of Impression bit, taking on "Mary Had a Little Lamb" as Spears, and then showing off her vocal chops with an Aguilera-sounding rendition of "The Wheels on the Bus."

For his part, Fallon did a nice job channeling Sting and Aaron Neville. The two also took turns doing versions of The Weeknd's "I Can't Feel My Face."

Grande has been on the press circuit this week. Earlier in the day, she paid a visit to "Good Morning America" where she opened up about the doughnut licking incident.
