Images showing a undressed Jlaw have been uploaded to the internet included in a package of hacked pics in the second such leak of hacked personal videos of stars by TMZ and other online sites such as Huffington Post.
The list of stars involved in the release also includes soccer player Hope solo and Kim Kardashian. New photos of Lee Sobieski have also been released in this latest update.
It is not clear when the pics were from but investigations into the hacks are currently in progress by the FBI.
A few weeks ago over 100 famous women were targetted by hackers who took over a hundred of naked pics and sex tapes from their personal phones and released on the web.
The original leak also included celebrities Arianna Grande, Kirsten Dunst and Victoria Justice.
Reps for Kate Upton released a statement on their twitter accounts saying they were verifying the authenticity of the photos.
