Dodger666 - "We will have to agree to disagree, Andy.
There is no way I would label this woman as a "Celebrity". I would also say she is more infamous for what she hasn't done rather than famous. A true celebrity will be a celebrity for ever."
Fair enough, although I think use of the terms 'celebrity' and 'star' are sufficient to emphise the gap between the two states of fame.
A 'celebrity' is famous for doing nothing, and will have a brief but seriously high-profile career before burning out because lack of anything concrete - music, acting, something, anything - means that people tire very quickly of one individual, who is instantly replaced by another.
A 'star' is someone whose fame is based on a body of work, music, film, television, books, or similar, and they have a lasting career based first and foremost on their inherent talent.
So, on that basis - 'White Dee' is a celebrity, Paul McCartney is a star.
