Ariana Grande is a pop star in her own right, but the former Sam and Cat star can also perfectly imitate those who came before her. On Tuesday night (Sept. 15), the "One Last Time" singer stopped by The Tonight Show Starring Jimmy Fallon to promote her new fragrance Ari by Ariana Grande and to announce her new single "Focus," but when she wasn't chatting up the talk show host, she was showing off her impressive impressions of Britney Spears, Christina Aguilera and Celine Dion.

Grande and Fallon whipped out the wheel of impressions, wherein songs and celebrities are "randomly" selected to be performed. First up, Grande had to tackle "Mary Had a Little Lamb" in the style of Spears, and even though she didn't actually sing a single word, she slayed the performance with that signature baby voice.

Grande's real star impression, however, was Aguilera performing "The Wheels on the Bus." Bringing her own big diva voice to the stage and mixing it with Aguilera's bombastic throaty voice. For good measure, Grande even threw in the "heh" sound Aguilera adds at the end of all her big runs, emphasizing its importance.

Though the Aguilera impression was epic, Grande capped it all off by singing her "Love Me Harder" collaborator The Weeknd's new single "Can't Feel My Face" as Dion, even speaking in a French accent. Those old comedy chops of hers sure still shine through.

Grande wasn't just on The Tonight Show to talk fragrances and sing like other celebrities - she has music of her own on the horizon too. After teasing a single announcement earlier in the day, Grande finally announced when the lead single off her third album Moonlight is due to arrive. "My first single off my new album is coming out on Oct. 30," she shared. "It's called 'Focus.'"
