Watch Justin Bieber, Diddy, Skrillex & Diplo Close Out Ultra Music Festival 2015
After Skrillex threw down solo with everything from Sum 41 to his classic “Cinema” remix he turned Ultra 2015 upside down with the help of Diplo, as they turned the set into a Jack U rager. But that wasn’t enough, together they brought out not just Justin Bieber (who we knew about), but also Diddy. Puff Daddy helped close out mainstage UMF. Just let that think in for a second, as you watch the clip after the jump.
