AceShowbiz - %cSkrillex% invited some of his pals to the stage as he brought the 2015 Ultra Music Festival in Miami to a close on Sunday night, March 29. Among those were %cDiplo%, with whom the 27-year-old DJ formed %cJack U%, and %cJustin Bieber%.
The Canadian singer took the stage towards the end of Skrillex's set, assisting him and Diplo on "Where Are U Now" from Jack U's debut album "Skrillex and Diplo Present Jack U" that was released last month. Showing up in a black T-shirt, pants and a cap, Bieber lip-synced the first few lines of the song before showing off some dance moves in front of the cheering crowd.

Bieber's appearance during Skrillex's headlining set at Ultra Fest came just a day after he surprised the crowd at %cAriana Grande%'s Miami show. On Saturday, the "Baby" hitmaker unexpectedly showed up at Miami's American Airlines Arena and messed up the lyrics of "Love Me Harder" as he joined the former Nickelodeon star onstage.
