The "Beauty and the Beast" actress' spokesman said the images aren't nude photographs, but instead show the star trying on clothes.

Watson, a UN Women goodwill ambassador, was also threatened in 2014 with a leak of nude images after delivering a speech on gender equality.
Two men - one from Pennsylvania and the other from Chicago - were recently sentenced in connection with the 2014 celebrity nude photo hack. Jennifer Lawrence, Ariana Grande, and Kate Upton were among the actresses who fell victim to the iCloud hack.
