Pictures circulating online which appear to show Justin Bieber naked have reported been exposed as fakes.

The two 'selfie' shots, which have spread among fans on Twitter.com, were thought to show the star completely nude while holding the camera up.

However, a source tells editors at TMZ.com that the photos are "100 per cent fake", and the snaps show off nothing more than good Photoshop skills.

Even though the man in the pictures does not show his face, fans began speculating that it was Justin as the tattoos on the body seemingly matched the singer's, but TMZ.com reports the star is "laughing off" the photos.

It is not the first time the Canadian pop star has been hit with a nude photo scandal. In October (15), Justin was pictured naked outside his villa in Bora Bora, French Polynesia, while on holiday with model Jayde Pierce.

His lawyers clamped down on any further publication of the shots by circulating cease and desist letters.

A representative for Justin has yet to comment on the latest nude snaps report.
