Did Princess Diana really dishonor the royal family?

Or is that just a Myth? I hear all kinds of wild stories about her. I heard that she was pregnant with a baby when she was killed and she wasn't even married yet. It was her middle eastern boyfriend. They had plans to move to Southern California. To me it just sounds like someone's sordid tales and there is no confirmation of which. She would still be alive and kicking today if only she wore her seatbelt. Mercedes-Benz is about as safe as they get. Especially since it was the S-Cl which is a full size sedan. Very safe indeed.
