Pictures of Oscar-winning actress Jennifer Lawernce have appeared over the internet, with reports suggesting that an anonymous hacker was able to post the images after gaining access to the actress' mobile phone via Apple's online storage system iCloud.
A spokesperson for Lawrence, confirmed the authenticity of the photos, adding: "This is a flagrant violation of privacy.
"The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence."
Pictures of the 'Hunger Games' actress in various states of undress have been posted on the bulletin board website 4chan.
However, it appears that the hacking scandal extends well beyond the explicit photographs of Lawrence, with more than 100 A-list celebrities thought to have been targeted, including reality TV star Kim Kardashian, Rihanna and Ariana Grande.
One confirmed victim of the hack is 'Final Destination' actress Mary E. Winstead, who took to Twitter to voice her anger.
