Recently Justin Bieber unveiled his hit single Where Are U Now but this was not the first time that fans had the opportunity to hear the song.

Justin actually wrote the song back in 2009, when he was 15-years old. At the time it was untouched by producers Diplo and Skrillex who transformed the single for it's release this year. 

Justin is seen in a video performing the song while playing the keyboard during a performance on KiddKraddick in the Morning. 

Now the song is thought to be one of the biggest dance anthems of the year, but back then it sounded entirely different.

 
The video is a reminder that Justin has got some serious musical talent as he belts out the heartfelt ballad. He has spoken about the original version of the song before. He told Jimmy Fallon that he thought it was "incomplete."

So naturally, because this is how the land of celebs works, he sent it Skrillex:

"Skrillex did his thing to it and made this weird sound in the hook and called it a dolphin sound."

The rest is dance music history that Justin's fan absolutely love. They love The Biebs and his music so much in fact that at a recent event in Paris, some of his fans came to blows. 

Hollywood Life reports that a physical fight occured between female fans while they waited for Justin outside a studio in the city. The brawl apparently turned bloody as the crowd got worked up waiting for the singer to emerge. 

Justin is due to release a new album in November and since his latest single What Do You Mean? was released he has been a huge press tour. It looks like his fans have certainly not forgotten about him then. Bieber fever could be back before we know it.
