A version of one of Justin Bieber's songs which has been slowed down by 800% has become an internet hit.

The unique rendition of 'U Smile' transforms the track from a hip-hop pop song into a seemingly chillout number.

It has been created by musician Nick Pittsinge using a special piece of production software.

'U Smile' is taken from the 16-year-old's smash hit debut album 'My World'.

As previously reported, Bieber has been approached by Kanye West to work on a song together.
