Nude and risque photos of Jennifer Lawrence and other massive stars, such as Ariana Grande, Kate Upton and Victoria Justice, reportedly leaked online Sunday. The images first appeared on the controversial /b/ thread of 4chan, an 'image-based bulletin board where anyone can post comments and share images.'
According to BuzzFeed, the pictures were allegedly retrieved through hacking celebrities' phones after an Apple iCloud leak. The anonymous hacker also claimed to have explicit videos of Lawrence and over 60 nude photos.
A spokesperson for Jennifer Lawrence released a statement confirming the photos are real and warned anyone who posts the stolen images of potential consequences.
"This is a flagrant violation of privacy. The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence," the statement read.
A rep for Ariana Grande wrote BuzzFeed in an email, 'The photos are completely fake.'
Other stars have taken to Twitter to addressed the alleged leak. Victoria Justice tweeted that the photos of her are not real.
Horror movie actress Mary Elizabeth Winstead, whose photos were leaked, also condemned the hack on her social media accounts.
According to the Huffington Post, the Los Angeles Police Department has 'no knowledge of the hacking at this time,' and the FBI and Apple have not responded to HuffPost's request for a comment.
The implications of being caught posting stolen photos online can be huge. In 2012, a man was sentenced to 10 years in prison and ordered to pay $66,179 in restitution for hacking celebrity email accounts and posting intimate photos of Scarlett Johansson, Mila Kunis and more online.
Sunday's hacker also posted a 'master list' of stars whose NSFW photos and videos he claims to possess. Click through our gallery above to see which celebrities allegedly got hacked.
