“I want to make one thing clear. I’m just hosting. No, I’m not going to make this about me. “I’m just going to have fun, take it easy and, yeah, keep it low key,” she said.

A beat later, Grande accepted a microphone from off-camera to sing an original song about her plans to resist the temptation to act like a “diva.”

The song obviously showed off Grande’s impressive vocal range, despite her promise to do so not sing her “favorite notes” – “not C, D, B, A or G.”

It also featured a 1-2-3 of Grande’s impressions: a pair of Spears-style “Ooh baby babies,” a quick riff on Cyrus and a Stefani parody of the tune of No Doubt’s “Don’t Speak.”

The opener then took a breathtaking turn as Grande got a Broadway-worthy lift, courtesy of a backup dancer, and was also joined onstage by Bowen Yang in full Glinda drag.

The crowd at Studio 8H weren’t the only ones gobbling up Grande’s hammy. Viewers at home were also knocked out by her musical monologue.

“She basically did what needed to be done. She went from singing, to acting, to humor, to dancing. She is one of a kind. No one does it like her,” one viewer wrote alongside a snippet of Grande’s monologue posted on the official “SNL” Instagram account.

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