Over the weekend, Ariana Grande and Calvin Harris hit the stage to headline the Billboard Hot 100 Festival on Jones Beach in New York.
Ariana headlined the opening night of the festival, delivering one hit after another, and even bringing out good friend Mac Miller to join her on stage during her performance of "Into You."

On the second night, Calvin headlined, spinning several of his newest hits, like "This Is What You Came For" and "How Deep Is Your Love.” He closed the night with "Blame" and a massive confetti explosion.
Other performers at the second annual festival include Rachel Platten, Fetty Wap, and J. Cole.
