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…
