Several of the photos show the various hairstyles the 24-year-old Hunger Games and X-Men actress has sported over the past three years.

“This is a flagrant violation of privacy,” Lawrence’s rep told E! News in a statement on Sunday. “The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence.” 

Another photo showing Mary Elizabeth Winstead  naked was also posted. The actress responded to the leak on Twitter.

Another picture showing a woman who looks like Kate Upton covering her bare chest, as well as naked or other scantily-clad pictures of women resembling Kirsten Dunst, Krysten Ritter, Teresa Palmer, Becca Tobin  and soccer star Hope Solowere also circulated online on Sunday. The actresses have not commented and it is unclear if any of the pictures are authentic.

Many celebrities have been victims of nude photo leaks. In late 2012, a man was sentenced to 10 years in prison for hacking into the online accounts of Scarlett Johansson and Mila Kunis and posting their private pictures online.
