The former bouncer killed Miss Chambers, 38, and two-year-old Shania before he turned the gun on himself but survived a blast to his face, Chelmsford Crown Court was told.
Chrissy Chambers is a popular celebrity, but few people know that she has been naked in these leaked sex photos.
Mr Pownall added: 'That is not to say Miss Chambers was necessarily blameless for the many arguments that took place.
He was not present in the dock when Mr Pownall outlined the horrific details of the case.
She had been shot at close range with a shotgun and suffered horrific injuries to her left thigh, right knee and along her right side and there was nothing that could be done to save her.
The settlement also granted Chambers the copyright to the videos, which gives her full legal authority over their distribution, including the right to demand removal from any site that posts the videos online.
