Authorities Close in on Celeb Hacker Ring

Vanessa Hudgens met with law enforcement today over nude photos and video that were hacked from her Gmail account, and TMZ has learned authorities believe as many as 50 other celebrities may be victims as well.


Sources tell us ... the FBI is conducting a wide-ranging investigation into a ring of hackers, and agents believe all 50 celebs trace back to one person -- possibly the ringleader.

Sources say one of the other celebs is Scarlett Johansson, who had a nude picture hacked from her iPhone.

The ring has been hocking some of the photos and video to various Internet sites and others, but we're told the primary motivation is not money -- it's the thrill of hacking.
