A Las Vegas audience was treated to a Nicki and Ari reunion last night (April 8), as Ariana Grande debuted a new Dangerous Woman track and welcomed Nicki Minaj onstage to perform The Pinkprint collab "Get On Your Knees" live for the first time ever.

The two co-headlined at the T-Mobile Arena, and fans hoping one would join the others' set were not disappointed. The searing case of FOMO I have right now is real, it's slightly soothed by some fan-captured video.

Ariana's latest is rumored to be called "Leave Me Lonely," and features raspy-voiced late '90s/early aughts star Macy Gray sounding Nina Simone-ish (Gray was not present at the concert). The sultry number is a close cousin to the album's title track, more torch song than "Be Alright"-style bop.

The footage of Nicki and Ariana's "Get On Your Knees" live debut is lower quality, but we'll take it. The rapper and the singer/ace celebrity impressionist both shared images from the show on Instagram Friday morning, with Nicki writing, "ARI!!!!! 😍😛😘😛 thank u for sharing the stage w/me my love."
