Ariana Grande really had us on the edge of our seats during Arichella during the first weekend of Coachella 2019. Being only the fourth female artist to headline the Southern California festival and the youngest ever, the 'Thank U, Next' singer pulled no punches during her performance. Leading up to the event, Ari teased an *NSYNC appearance by posting videos of herself at their concert when she was young. Even though Justin Timberlake wasn't there, the boy band plus Miss Grande sent all back. Not only did she bring out the best boy band ever (yea I said it), she was also joined by Nicki Minaj and, surprisingly, Diddy and Ma$e to honor Mac Miller, Nipsey Hussle, Tupac and Biggie. Check out a full recap below.
