Nude photos purportedly showing many top stars, including Lawrence and Rihanna were circulated on social media Sunday, in an apparent massive hacking leak, U.S. media reported. Word of the images began spreading early Monday amid reports that the photos had been obtained by hacking iCloud accounts, Mashable and other media reported. The leaked photos prompted angry reactions from the stars who had been exposed. | AFP-JIJI
