Pictures showing a undressed Jlaw have been released as part of a collection of hacked pics in the second such release of hacked personal videos of celebs by 4Chan and other online sites such as Huffington Post.
The list of celebs involved in the release also includes oscar winning actress Jennifer Lawrence and Kim Kardashian. New pictures of Lee Sobieski have also been leaked in this latest update.
It is not clear when the pictures were developed but investigations into the release are currently being made by the police.
A few weeks ago over 100 celebs were hacked by hackers who stole hundreds of naked pics and sex videos from their personal accounts and leaked on the internet.
The original collection of images also included celebrities Kate Bosworth, Selena Gomez and Jessica Brown Findlay.
Representatives for Kate Upton made an announcement on their twitter accounts saying they were investigating.
