Ariana Grande does spot-on impressions of Celine Dion and Britney Spears on “SNL.”

“I just want to make one thing clear. I'm just a host. No, I won't say that about myself. “I'm just going to have fun, take it easy and, yeah, I'm just going to keep it low-key,” she said.

Moments later, Grande took an off-camera microphone to belt out an original song about her plans to resist the temptation to act like a “diva.”

The song, of course, showcased Grande's impressive vocal range, despite her promise not sing your “favorite notes” – “not C, D, B, A or G.”

It also included a 1-2-3 break of Grande's impressions: a few Spears-style “Ooh Baby Babies,” a brief riff on Cyrus, and a Stefani parody to the tune of No Doubt's “Don't Speak.”

The opening then took a breathtaking turn when Grande received a Broadway-worthy lift thanks to a backup dancer and Bowen Yang also took the stage in full Glinda drag.

The audience at Studio 8H wasn't the only one eating up Grande's muttonness. The audience at home was also thrilled by her musical monologue.

“She actually did what needed to be done. She has gone from singing to acting to humor to dancing. She is unique. Nobody does it as well as her,” one viewer wrote alongside a snippet of Grande’s monologue posted on the official “SNL” Instagram account.

“Ariana is truly made for SNL. She has an amazing ability to impersonate other artists,” a third viewer wrote on YouTube.
