Bieber puts the audience in their place.
Justin Bieber Leaves ‘Purpose’ Track About Selena Gomez On Cutting Room
The way he went about it came off bratty, but the comments on YouTube mostly defend him.
"I can't stand the little shit, but he didn't anything wrong here. He just synched them into the right rythm," one user said.
"Dont make a big deal out of this, this wasnt disrespectful, he corrected them lmao. I wouldve done the same," said another.
"It's extremely difficult to sing on key/tune/beat when the beat is off. And being a drummer it means even more for Justin."
It's the second time during his Purpose promotional campaign where the 21-year-old lost his cool for a moment. Last week, Bieber told several girls in the front-row during a show to stop tugging at his leg because he might fall on the slippery stage. They didn't comply, and he cancelled the entire show.
He said of that incident, "In no way did I mean to come across mean, but chose to end the show as the people in the front row would not listen," he added. "Hopefully people will understand where I am coming from. I don't always handle things the right way but I'm human and I'm working on getting better at responding not reacting."
