A publicist for Jennifer Lawrence says the actress has contacted authorities after nude photos of her were apparently stolen and posted online.

Intimate images of the Oscar winning actress began appearing online on Sunday and nude images purported to be of other female celebrities were also being circulated online. The source of the leak wasn't immediately known.

Lawrence's publicist Liz Mahoney calls the posts "a flagrant violation of privacy." She says Lawrence, the star of "The Hunger Games" movies, has asked authorities to prosecute whoever is posting the photos. Mahoney declined to provide any further details.

The FBI has investigated previous leaks of nude celebrity images, including leaks involving actress Scarlett Johansson, singer Christina Aguilera and TV sports reporter Erin Andrews.

FBI spokeswoman Laura Eimiller declined comment.
