Feds probing leak of purported nude photos of Scarlett Johansson

Nude snapshots of actress Scarlett Johansson – apparently filched from her cell phone - popped up on the web yesterday just as the FBI confirmed to a popular celebrity website that it has launched a probe into celebrity hacking.

One foggy shots depicts a woman who appears to be Johansson taking a shot of herself laying down, topless. Another shows her shooting a picture of her bare backside in a full-length mirror with a cell phone.

“The FBI confirms we are investigating computer intrusions of high profile figures,” a spokesman told RadarOnline.com.

Johansson was one of about 50 celebrities, including Jessica Alba and Vanessa Hudgens, mentioned in March reports as having been victimized in March by a hacking ring that was cracking cell-phone accounts in search of dirt, according to the Los Angeles Times.
