I heard stories about her sleeping around before she became mainstream. Wouldn't know if they were true or not though. Amazing what an average voice, decent looks and great PR can do.
I heard that too, from somebody that used to work with her at Abercrombie (I think, could have been one of those other shops).
Her PR team is ridiculous. They're pushing her and Cara to the point where it becomes really obvious and forced. People are starting to realise that it's a case of style over substance.
