Hell Paris Hilton had a porno out without her permission.
Unlikely that it was with out her permission. Besides the camera belonged to the dude, she was fully aware that she was being filmed. In private matters particularly non-professional aspects, legalities such as release rights don't do anything. Unless, the camera was hers and he stole it and released it, then she would have a case. However, it was not.
