Poor, poor Kate Moss. The wafer-thin supermodel copped to doing a little blow, and whoosh, her career is gone with the wind. First she was canned by H&M, and now Burberry has backed out of a deal with her and Chanel has declined to renew her contract. (Even her boyfriend, rocker Pete Doherty, is reportedly miffed at her.) Honestly, did any of these people really think she maintained her stick figure by doing Pilates and eating celery stalks?
