Ariana Grande Just Became A Member Of *NSYNC At Coachella

Ariana Grande just lived out all her '90s dreams by bringing *NSYNC on stage at Coachella.

Grande introduced the iconic boy band -- sans Justin Timberlake -- to the crowd at the Californian festival, announcing that she's been waiting a long time to perform with the group.

"Coachella, I’ve been rehearsing my whole motherf***ing life for this," she said before they all launched into her hit "break up with your girlfriend, i'm bored".

The new *NSYNC lineup -- with Ari replacing JT -- then went straight into their 1997 bop, "Tearin' Up My Heart" with Grande nailing the choreography as the group's new leader.

Ariana's so-called Ari-Chella set also featured Nicki Minaj, who jumped on stage to sing their hit "Bang Bang" and "Side To Side".

Grande also brought out Mase and P. Diddy for a cover of the Notorious B.I.G's "Mo Money Mo Problems" and finished up the set with an emotional performance of "thank u, next".

Fans were 90 percent sure that *NSYNC would make an appearance during Grande's Coachella set -- after she left a trail of boy band breadcrumbs on her Twitter feed this week.

Ari posted a video of herself bopping along to "Tearin' Up My Heart" a few days ago with the '90s baby writing that it was "the best medicine" but now we know she was just rehearsing her Coachella set in front of our very eyes!

She also confirmed to *NSYNC's JC Chasez that, yes, the mic was definitely on ahead of their rumoured Coachella performance.

But the most vital piece of the puzzle came along with some archival footage that proved that the seed for this Coachella collaboration was planted a good 20 years ago.

Ari posted a clip from a live *NSYNC performance from the late '90s, which pans straight from Justin Timberlake crooning along to "It Makes Me Ill" to a baby faced Ariana, singing along in the front row. Kismet!

Timberlake had hinted earlier this week to a crowd in Connecticut that he might be retiring, announcing that he was "probably never going to do this again" as he wrapped up his Man Of The Woods tour.

Grande will perform again next week for the second round of Coachella.
