The FBI is looking into who might have released nude photos allegedly hacked from the private cell phone of Scarlett Johansson
, reports FoxNews.com
, quoting an official from the bureau.
The photos in question surfaced online Wednesday, and TMZ
reports that Johannson, 26, made the request that the FBI track down the perpetrators.
The FBI is already investigating some 50 other celebrity email accounts that might also have been hacked, including those belonging to Vanessa Hudgens
and Jessica Alba

Three months ago, alleged hackers claimed to have nude photos of Blake Lively
, whose rep was quick to threaten legal action against any website that made the photos public.
Other reported victims of hackers include Selena Gomez

, Christina Aguilera
, Ali Larter
and Miley Cyrus
