Pictures showing a unclothed Kim Kardashian have been leaked as part of a package of hacked images in the second such release of hacked personal pictures of stars by 4Chan and other websites such as Gizmodo.
The list of stars involved in the release also includes actress Vanessa Hudgens and child star and actress Mary-Kate Olsen. New images of Lee Sobieski have also been leaked in this latest update.
It is not possible to determine when the pictures were taken but investigations into the leak are currently being made by the FBI.
Earlier this month over 100 celebs were targetted by hackers who took over a hundred of naked pics and sex videos from their personal phones and leaked them to the public.
The original collection of images also included celebrities Arianna Grande, Kirsten Dunst and Victoria Justice.
Representatives for Kate Upton made an announcement on her official website saying they were investigating.
