Justin Bieber has posted a 'Making of Believe' webisode online.

The clip, which will be the first of many as the release of his new album 'Believe' nears, sees the singer lay down some vocals for the track 'As Long As You Love Me'.

He can be seen with his old, longer haircut as he works with his producers on the song. Tweeting about the video, Bieber said:

"Took long enough. here it is. Webisode : Making of #BELIEVE - AS LONG AS YOU LOVE ME."

Bieber meanwhile has been something of a naughty teenager recently after gaining access to his manager Scooter Braun's Twitter account, posting a series of prank messages.
