Jennifer Lawrence's Nude Photos Leak Online

A 4chan user claims to have released nude photos of several female celebrities in a major hacking.

The hacker said that he or she leaked photos of Jennifer Lawrence, Kate Upton, and a host of other stars.

A rep for J.Law confirmed that the images are real.

"This is a flagrant violation of privacy," the spokesperson told HuffPost. "The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence.”

The Los Angeles Police Department said that they have "no knowledge" of the hacking "at this time."

The hacker claims to have more NSFW pics as well as videos. The user offered to release more media in exchange for money.

Victoria Justice, who was also targeted in the hack, said that the photos aren't real.

"These so called nudes of me are FAKE people," she said. "Let me nip this in the bud right now. *pun intended*"

Horror movie actress Mary Elizabeth Winstead lashed out at the hacker on Twitter.

"To those of you looking at photos I took with my husband years ago in the privacy of our home, hope you feel great about yourselves," she said. "Knowing those photos were deleted long ago, I can only imagine the creepy effort that went into this. Feeling for everyone who got hacked."

Kate Upton's spokesperson told HuffPost that they are "looking into" the allegations.
