Scarlett Johansson’s powerhouse legal team  threatened to sue a small tabloid web site that published naked photos of the Lost in Translation beauty -- even though the site knew the pictures were stolen.

(RadarOnline.com was first to report the FBI was investigating the theft of the photos, and chose not to run them).

Lynda B. Goldman of the powerhouse law firm Lavely & Singer fired off a letter Thursday to RumorFix.com,  a relatively unknown tabloid web site launched by Dr. Phil McGraw’s son Jay, who also is Executive Producer of NBC’s The Doctors.
