When the power went out at a recent show, Justin Bieber powered on - and what resulted was a mass singalong to "Boyfriend" with all his fans.
The outage, which lasted over 40 minutes, frustrated Bieber but he decided to soldier on.
"I'm sorry the power is out... You guys have always had my back. I'm going to sing "Boyfriend" and you're going to sing it back to me," he told his fans.
The performance was a part of an exclusive show, which was filmed for an NBC special.
