LOS ANGELES (CBS) — Celebrities such as Scarlett Johansson say racy pictures recently leaked online were stolen from their cell phones.

Mila Kunis’ seductive photos of Justin Timberlake and nude photos of Johansson were among those leaked on the Internet.

Celebrity Web site Radar Online says it’s speaking with the FBI after someone reportedly came to editors with the hacked photos.

Radar Online recently reported that personal photos of Julianne Hough and Miley Cyrus, as well as a script from Tom Cruise’s new movie, had been leaked.

The FBI isn’t confirming any details.
