I think the difference between Diana and celebs such as Madonna, etc., is that Diana did not financially gain - as far as I know - from her celebrity status. She was selling the charity of the moment, in an effort to raise funds for that charity. I don't believe she was ever compensated for her appearances. Celebs who are looking to stay in the public eye for fianacial gain are selling themselves - it how they make their living. Diana was reported to be worth about $77 million at her death which I had read was expected to go to her younger son Harry, since under England's inheritance laws William will inherit the duchy of Cornwall from his father which is massive. She would benefit if the charity paid her transportation, hotel bill, etc., does anybody know if she received any kind of honorarium for her appearances? If not, I think that is a very important distinction between "Charity Promoting" personages and other celebs.
