The 19-year-old abruptly left the stage in Buenos Aires because his manager says Bieber came down with food poisoning, The Associated Press reports.
Bieber's manager, Scooter Braun, says the singer performed for nearly an hour against doctor's advice. "I'm not feeling too good, I think I'm out of energy," Bieber said as he blew the crowd a kiss and walked off stage. He later posted a photo of himself on Instagram receiving IV fluids.
Bieber's quick exit drew boos from the audience, some of whom paid up to $320 to see him in concert. No word yet on whether Bieber plans to offer a refund. He is next set to perform in Chile on Tuesday.
