Watch This: Justin Bieber And Diplo Join Skrillex For His Headlining Performance At UMF

Before the final day of this year’s edition of Ultra Music Festival, Miami there were rumours circling about a possible cameo by Justin Bieber during Skrillex and/or Diplos set (much to Electronic Music fans’ ire). Despite receiving a lot of negative comments all over social media, Ultra ensured the rumours were indeed true. Bieber made a special guest appearance during Skrillex‘s Mainstage-closer! Lip syncing to their recent smash hit ‘Where Are U Now’ (which didn’t go down well with a lot of people), Bieber danced and even got on top of the decks while fireworks closed the mainstage.
