The show will always go on for Justin Bieber!
Monday night at a private show at Harlem's famed Apollo Theater, the power went out near the end of the performance.
"Me and @ludacris blew up the power at the @ApolloTheater," the 18-year-old pop star tweeted. "Haha. Epic. #beastmode"
Of course, the Biebs' loyal fans didn't leave him hanging…
They provided the music for him! "I'm gonna sing it, and I need everybody to sing it with me," he told the crowd, as shown in a YouTube video. The audience happily obliged, hitting every word of "Boyfriend" in unison as Justin's drummer provided a beat.
"A night none of us will ever forget!! That is how u end an #AllAroundTheWorld run!!! With no power for the last song...my fans sang it 4 me," Justin tweeted.
The excited singer added: "What I saw tonight! My fans! My Beliebers! They stepped up for me! I love u! I will never forget 2nite! That was the way a show should end.."
Justin's manager, Scooter Braun, told MTV News the power outage went on for more than 40 minutes. J.B., naturally, took the opportunity to charm his fans, joking that it was "all the hot girls in here" that caused the technical glitch.
Apollo rep Nina Flowers gave Bieber props for his professionalism. "He could have stopped," she said. "He could have not gone on and said, I did everything, but he came back on."
The show was taped as part of an NBC special expected to air later this week in celebration of his album Believe. (E! and NBC are both part of the NBCUniversal family.)
