Coachella: Ariana Grande becomes fourth woman to headline, brings out *NSYNC members and others

They then sang their hit, "Tearin' Up My Heart," while Grande sang and did the iconic dance moves with the group. In a cute twist, the video screens showed ripples and old numbers as though the audience was watching a VHS tape of the performance. The guys thanked the crowd and left. Grande said "I can die now" as they exited. 

But that was just the start of the surprise guests. Moments later Nicki Minaj arrived to sing "Side to Side." The two left the stage, walking out onto a bridge along with about 12 dancers. While there, they also sang "Bang! Bang!" the hit song they collaborated on with Jessie J. That part was not without its technical problems as Minaj's microphone didn't seem to always be working. 

The guest list wasn't closed yet, though, later in the set P. Diddy and Mase came on to sing "Mo Money, Mo Problems" as images of Biggie Smalls showed on the center screen which was planet-shaped and almost planet sized. 

Despite all the special guests, this night was about Ariana and she didn't disappoint – it was "Arichella" as the hashtags say.

She held the audience captivated throughout the night whether it was poppy dance hits like "7 Rings" or more emotional songs like "Breathin" which she sang while being circled by about a dozen women playing violins.
