"We have nude/sexual photos of Demi Lovato and was wondering if you would like to buy them ... The girl in the middle row, last pic is our friend and is a girl Demi had a fling with for some time on and off," the website published.
The seller continued in a message to the site saying, "After Demi got with Wilmer our friend called it off because she didn't like being played, she sent me these pictures that Demi sent her as a joke and I have no use for them ... There are about 20 total, not all have indication they are of her except some have her tattoos in ones you cannot see the face."
As Radar exclusively reported last week, 20 photos are for sale but Radar was unable to verify that the breast-baring images were authentic and chose not to publish them.
The woman in the images has some tell-tale signs suggesting it is indeed the former Sonny with a Chance actress — like the same tattoos, including 12 black birds on her right forearm — but other photos appear to look nothing like her.
It is not known how the naked images were leaked and whether Lovato is the victim of a cyber crook, however, her name has been brought up in the past as someone who was hacked.
A hacker was reported to have nude photos and videos of at least 50 female celebrities – including Scarlett Johansson, Selena Gomez and Miley Cyrus – after they hacked into their cell phones and other devices to obtain the compromising images.
