Justin Bieber Sings ‘Boyfriend’ Acapella After The Apollo Theater Loses Power [Video]

Justin Bieber was in New York to promote his new 'Believe' album that came out Tuesday.  He was performing at The Apollo when all of a sudden, the majority of the power to his instruments was lost.

The Biebs kept a cool head and actually used the technical difficulty to make a really cool moment for the crowd.

I have to admit, for as much crap that Bieber gets from doubters, he continues to prove them wrong on a daily basis.  What he does in the video shows a huge amount of stage presence and composure.

The last time I saw a moment like this was when Ludacris performed at Saginaw Valley State University.
