UPDATE: The FBI and Apple, which operates the online file storage service iCloud, have responded to the nude photo leak.
Naked and scantily-clad pictures of who appears to be Jennifer Lawrence, as well as other racy pics resembling other celebrities, surfaced online on Sunday during Labor Day Weekend, sending Twitter and Reddit users into a frenzy and spurring speculation about another celebrity hacking case.
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.
