Tonight at the 2016 Grammy Awards, Justin Bieber and Jack Ü—a.k.a. Skrillex and Diplo—performed their Grammy award winning (!) 2015 smash hit “Where Are Ü Now” live on television for the first time ever. Opting out of nob turning for the occasion, Skrillex wielded a guitar and Diplo banged away at the drums while a small string section played behind them. Justin Bieber also performed "Loved Yourself." Watch it all go down above.
