*Sony is trying to pull a fast one on Michael Jackson fans with their upcoming MJ release.

According to family members, an album the label is attempting to push out by Christmas is not authentic.

Sources tell TMZ Mike’s children, Paris and Prince, believe some of the songs on the album are fakes – not their father’s voice. However, Sony is convinced all of the songs are the real deal.  

Howard Weitzman, lawyer for the estate, tells TMZ he had experts listen to the tracks and all of the experts concluded it’s Michael’s voice on all the tracks.

Other members of the family also believe the tracks are fake. As of now, no lawsuits have been filed.
