This year's festival, which wraps up on April 21, is headlined by Childish Gambino, Ariana Grande and Tame Impala. The singer then performed "Break Up With Your Girlfriend, I'm Bored", a song that samples the No Strings Attached 'NSYNC album track "It Makes Me Ill" - and, to the audience's pleasure - Lance Bass, JC Chasez, Joey Fatone, and Chris Kirkpatrick joined Grande on stage.
Grande, who also performed her hit God Is a Woman, gave the quartet a huge introduction in saying, 'I've been waiting all my motherf***ing life to say this: *NSYNC!'
Prior to the show, Chasez fueled rumors of a reunion by tweeting, "Mic check, mic check one... two... is this thing on?!?", to which Grande later responded, "sure is".
A clip posted on Twitter showed Minaj not rapping to the beat, and Grande saying, "Can't hear anything".
Timberlake's absence was not acknowledged on stage, but parts typically sung by him in the band's hit single were taken over by Grande.
"Also how the f-- do y'all still sound and dance exactly like you did when my mom and i followed you around on tour when i was 5? thank you thank you thank you for your time and energy and i love you so much forever", she added.
