Nude Photos of Jennifer Lawrence, Kate Upton, Ariana Grande, Kirsten Dunst Leaked Online

Nude photos of a string of Hollywood stars including Jennifer Lawrence, Kate Upton, Ariana Grande and Kirsten Dunst have been leaked online by an anonymous hacker.

Lawrence's representative have confirmed that the photos are indeed authentic. In the pictures, the Hunger Games star is seen posing topless on a couch and drinking a glass of wine, wearing nothing but lace knickers.

The star's representative condemned the leak as "a vagrant violation of privacy," the Hollywood Gossip reported.

"The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence," the actress' publicist warned.

Nevertheless, the leak won't end with just a wave of defamatory pictures, say insiders.

"Even more photos and even videos will be released," a source told RadarOnline.com. "There are about 200 photos and two videos in total," the source added.

The source further listed Avril Lavigne, Krysten Ritter, Bar Rafaeli, Teresa Palmer, Brie Larson and Glee star Becca Tobin as the other victims of the anonymous hacker.

"There are many, many more images," the insider said.

Several pictures of Scarlett Johansson were leaked online by a hacker in 2011.

The Avengers star contacted the authorities following the leak. Johansson told Vogue in 2012, "I don't want to be a victim and say, 'Oh, well' and just hide my head in shame. Somebody stole something from me. . . . It's sick. I don't want people like that to slide."
