Bob forgot that people actually paid to see her naked. There's a long form video in which she appears naked, and also a book. She released both of them and used the fact that she appeared naked in them as publicity to sell them.
So. I don't think she was married then, at least not to this guy.
Lots of women do that and lots of lonely men pay for it. I don't see the issue.
Oh yeah and I think she was in Penthouse a long time ago
