My bet is that Lauren Sanchez leaked the stuff. She is a local here in LA, and knowing her history it is easy to believe that she is capable of it.
Your thinking that Sanchez leaked the pictures was mentioned on Fox. Their theory says that Sanchez wanted to speed up the divorce with Jeffry and his wife so Sanchez could get her relationship secured. It’s the spider and the fly story with the fly being Sanchez and Bezos and his fortunes in her web.
