Bieber reappeared sometime later to a barrage of screams, and told the
audience, “I’m sorry, I’m going to slow things down,” before taking to a platform on a crane to perform Fall on an acoustic guitar.
“It’s hard for me, you know, not feeling great and throwing up in front of a bunch of people.
“Will you love me even though I’m throwing up on stage?”"Okay, I wanted to give you my best show ever, so do you mind if I finish it?”
Later on, during Beauty and a Beat – his duet with Nicki Minaj, who provided her rap via a taped video, the singer vanished again and halted the show completely for a few minutes.
