Why do women say that other women, like Cheryl Cole are ' not real women' ?

I mean, she looks pretty real to me !! Surely it is very insulting for other women to talk of her and her ilk in such disparaging terms. To me she is just a girl from a north east council estate trying to make the best of her life. It is a shame there are not more like her with her aspirational outlook and hard working attitude. And yes people in the entertainment industry do work hard, the glamour and good fortune are the result of hours of work and slog. There are many women in places like to Kiev or also have such an aspirational attitude, especially with regard to how they present themselves. Why do women in England diss those who aspire to success and beauty ?
