The first ever Billboard Hot 100 Festival was not an event to miss. Jones Beach was packed with fans for two days in a row – which was no surprise considering some of the biggest names in music were performing. The Weeknd closed out the show on Saturday night, and Justin Bieber (with the help of Skrillex) ended the festival on Sunday night with his first New York appearance in three years. Also performing among the three stages was Little Mix, ZZ Ward, Lil Wayne, Halsey, Jason Derulo, MKTO, The Maine, X Ambassadors, Zella Day, Ryn Weaver, Misterwives, Tori Kelly, American Authors and more!
