Nude pictures thought to be of Rihanna have been leaked on 4Chan and Reddit today.

Two naked photographs allegedly of the singer have surfaced, in a second wave of the large-scale photo hacking, although their veracity cannot be established yet.

A spokesperson for Rihanna could not be reached.

New naked pictures allegedly emerged yesterday (20 September) claiming to be of Kardashian, Lawrence, Emily Ratajkowski, Vanessa Hudgens, Aubrey Plaza, Mary-Kate Olsen, Gabrielle Union, Hope Solo. Hayden Panettiere and Leelee Sobieski

Kardashian’s representative declined to comment.

Gabrielle Union and her husband, Dwayne Wade have since released a statement, via TMZ, describing the hackers as "vultures".

"It has come to our attention that our private moments, that were shared and deleted solely between my husband and myself, have been leaked by some vultures," read the statement.

"I can’t help but to be reminded that since the dawn of time women and children, specifically women of color [sic], have been victimized [sic], and the power over their own bodies taken from them. These atrocities against women and children continue worldwide." The couple also offered their sympathies for other victims of the hacking.

"For anyone out there also being affected by these and other hacking and hate crimes - We send our love, support and prayers," they said. "We have done nothing wrong."

The FBI and Apple are both conducting investigations into the apparent widespread invasion of personal accounts thought to be connected to the iCloud service.

A spokesperson for Lawrence said: ”This is a flagrant violation of privacy. The authorities have been contacted and will prosecute anyone who posts the stolen photos of Jennifer Lawrence.“

The anonymous hacker has complained about the moneyreceived for the images.
