As promised, Scarlett Johansson got the FBI involved when her phone was hacked and nude photos of her - ones she had never sent to anyone - leaked online, and it seems as if their investigation is finally showing some results; 35-year-old Christopher Chaney of Florida was just arrested in connection with the hackings of not only Johansson's phone, but also Mila Kunis's phone, as well as computer accounts and other devices belonging to more than 50 celebrities.

Basically, lesson of the day: Don't mess with Scarlett Johansson.

Chaney had a variety of aliases that he used to hack celeb's personal stuff with, and he used public sources to gather up data about the celebs he targeted. He was indicted on charges of "accessing protected computers without authorization, damaging protected computers without authorization, wiretapping and aggravated identity theft."
