A hacker reported to having obtained nude and intimate photos of Hollywood starlet and Oscar-winning actress Jennifer Lawrence has taken the internet by storm.

On Sunday, a 4chan user posted a list of celebrities that they claimed to have nude photos of. The hacker backed this up with a couple of ‘teasers’ of Jennifer Lawrence which quickly made rounds across file-sharing websites and image-boards, despite 4chan having removed the posts.

Lawrence’s spokesman confirmed that the photos are real 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.”

Lawrence has starred in blockbuster titles such as ‘X-Men: First Class’, ‘X-Men: Days of Future Past’, ‘The Hunger Games’, and ‘Silver Linings Playbook’ for which she won an Academy Award for Best Actress.

Other celebrities on this list include: Kate Upton, Avril Lavigne, Rihanna, Victoria Justice, and Ariana Grande (to name a few). Nickelodeon star Victoria Justice however denied that the photos of her are real tweeting, “These so called nudes of me are FAKE people. Let me nip this in the bud right now. *pun intended.*”

The anonymous hacker claims to have gained access via Apple’s online storage system iCloud. As of yet there are no more details. Apple has yet to respond to this widespread hack of celebrity accounts. This issue will no doubt raise awareness and concern among smartphone users who upload photos to cloud-based storage services.

Jennifer Lawrence is set to reprise her role as Raven/Mystique in the highly anticipated ‘X-Men: Apocalypse’, slated for release in 2016.
