The 2021 Billboard Music Awards kicked off with a fun-filled live performance by DJ Khaled, who was joined by H.E.R. and Migos to sing their hit We're Going Crazy. Unlike many of the performances over the past year and a half, the artists performed in front of actual fans outside of the Microsoft Theater in downtown Los Angeles, in what was likely one of the largest live crowds in months. Host Nick Jonas revealed in an interview with The Hollywood Reporter last week that there will be between 500 and 600 fans in attendance, who were treated to the performance by Khaled, H.E.R. and Migos first on Sunday afternoon.
