This was the best moment of the night Sunday at Coachella!
During Ariana Grande's set, she brought out *NSYNC (minus Justin Timberlake) to perform with her! Lance Bass, Joey Fatone, JC Chasez and Chris Kirkpatrick joined Grande on stage toward the end of her song "Break Up With Your Girlfriend," which samples *NSYNC's song, "It Makes Me Ill."
Then, the boy band sang "Tearin' Up My Heart," with Grande filling in Timberlake's spot.
They performed all the choreography and everything! Fans went crazy for the reunion!
