Photos: Billboard Hot 100 Music Festival - Day 2

Justin Bieber closes out the Billboard Hot 100 Fest on August 23rd, 2015 at the Nikon at Jones Beach Theater in New York (Benjamin Esakof/Roman's Rap-Up).

Day 2 of the Billboard Hot 100 Fest brought in even bigger crowds to see the likes of Nicki Minaj, Skrillex, Justin Bieber & countless others (including an appearance by Instagram-famed "Doug the Pug"). The day, anchored by Bieber, started out with hit-maker Fetty Wap taking to the beach stage, drawing so many to the small stage that it had to be closed, something Billboard definitely didn't anticipate. Following Fetty's knockout performance, all eyes were on the main stage for the rest of the night as artists like Kygo, Nicki Minaj, Skrillex & Justin Bieber took to the stage to give the ultimate finale to a great weekend of hit music.
