Justin wrapped his promotional tour with a show that saw him singing with fans after a power cut.

Justin Bieber told fans he will "never forget" his performance at the New York Apollo Theater last night (19th June), after a special moment that saw his fans serenading him.

Just hours ahead of releasing his new album 'Believe', Justin performed a special concert to promote the record at the iconic Manhattan theatre, as part of his current 'All Around The World' promotional tour.

However, towards the end of his set the power went out, stopping the use of stage instruments and some lighting, and Justin was forced to lead the crowd through an a capella rendition of his hit 'Boyfriend'

"A lot of emotions in the building. This one is special. This one is for MJ. #Apollo #BELIEVE," Justin tweeted shortly before the concert yesterday, after dedicating the show to the late Michael Jackson. "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's 'All Around The World' promo tour, which was filmed as part of an upcoming TV special, has seen the 'Never Say Never' singer perform across countries including Norway, England, France, Germany and Mexico.

"What I saw tonight! My fans! My Beliebers! They stepped up for me! I love u! I will never forget unite! THat was a the way a show should end," Justin also posted, before launching his album at midnight. "My new album #BELIEVE is finally Out on ITUNES and IN STORES!! Enjoy OUR ALBUM!! thank u."

Justin also received praise for his Apollo Theater performance from mentor Usher, who praised Justin's professionalism in continuing the concert despite the technical difficulties.

Usher posted: "Yo! I'm totally blown away by what I just heard…The Apollo performance was a major success for my lil bro @justinbeiber tonight. URIV."
