Nude photos of "Hunger Games" star Jennifer Lawrence, Kate Upton, Ariana Grande and Kirsten Dunst, among others, leaked online Sunday morning in one of the biggest celebrity hacking scandals in recent memory.

The images, which first appeared on image-sharing site 4chan, show most of the celebrities nude or in provocative poses.

A spokesperson for Lawrence blasted the hackers for their "flagrant violation of privacy."

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

Mary Elizabeth Winstead, another actress exposed in the leak, immediately took to Twitter to denounce the photos.

It's unknown how the risqu? photos made it to the web but celebrities have been a big target of phone hackers of late.
