Rihanna is the latest celebrity to become victim in what seems to be an ongoing phone hacking scam.
Early on Sunday, September 21, 2014, two nude pictures that appeared to be of the Pop singer were leaked onto Reddit showing off her bare ass and nipples.
Both pictures were reportedly taken during 'some sort of a fitting' this year.
We earlier reported that a second group of nudes were leaked online this weekend including Kim Kardashian, Vanessa Hudgens, Kate Bosworth, Meagan Good and at least 30 others. Gabrielle Union who's also a victim has confirmed she'll contact the FBI after her topless photos also leaked
Rihanna is however yet to comment on the issue.
