Law enforcement sources confirm with TMZ ... it was none other than the FBI that met with Vanessa Hudgens yesterday about the nude photos that were hacked from her Gmail account.
The FBI went to Vanessa's lawyer's office to meet with her in Century City, CA. The meeting lasted more than an hour and agents got info that we're told leads to one individual who may have hacked 50 A-list celebs.
We're told Scarlett Johansson was hacked by the same individual, who leads a ring of hackers.
