Johnny Depp's fiancee Amber Heard has become another victim of the ongoing Hollywood hacking scandal after more than 50 topless photos of the actress surfaced online on Sunday.

On Saturday, previously unseen steamy shots of celebrities including Kim Kardashian and Gabrielle Union, pregnant Hayden Panettiere and Vanessa Hudgens were posted on the internet.

The cyber criminals behind the leak continued to make waves on Sunday, when a new pair of explicit snaps of Rihanna were shared on 4chan.org.

Hours later, a haul of saucy pictures featuring Heard in various states of undress were also uploaded to the website. According to TMZ, the series of photos also includes one in which the beauty, above with Depp, can be seen holding up a sign directed at Depp, referring to the actor as "Tonto" - the character he played in the 2013 movie remake of The Lone Ranger.

The recent leak comes three weeks after similar saucy snaps were stolen from cloud storage devices belonging to the likes of Jennifer Lawrence, Kirsten Dunst and Kate Upton.

The FBI is investigating the case in a bid to identify those responsible for leaking the photos.
