The pictures, which have spread like wildfire over the Internet, show the 34-year-old in a variety of provocative poses lying on a bed, reported the Huffington Post.
Brook, who recently split from fiance David McIntosh, had previously said, "The only nude photos you'll ever see of me are the ones that I 'leak' and the ones that my head are superimposed on!"
However images, which feature the model, are currently being shared by various forms of social media.
The naked images are just the latest in a long line which have been shared during the 4chan hacking scandal, also known as The Fappening.
