Watch Ariana Grande perform “Imagine” on ‘The Tonight Show’

It was absolutely flawless.

Last night, Ariana Grande took to the stage at Jimmy Fallon’s The Tonight Show to perform her new single “Imagine” for the first time.

Unsurprisingly, Ari served major vocals during her performance. Backed by The Roots, the singer gave the dreamy R&B ballad a more festive approach: The sparkling synths were toned down to make way for soulful trumpet and sax. But the highlight of the four-minute-long performance? Grande’s Mariah-style whistle note, which she hit flawlessly three times in a row.

“Imagine” is Ari’s victory lap to end a massive year—and the live performance just proved her star power is at an all-time high.
