Fashion designer Roberto Cavalli has defended his decision to hire Kate Moss for a fashion shoot immediately after her cocaine disgrace, hailing her a "great professional". The catwalk beauty was photographed snorting the drug with then-boyfriend Pete Doherty in a recording studio in September 2005. She was subsequently axed from a string of lucrative modelling contracts, but Cavalli continued to use her despite the controversy. He says, "People asked me why I picked Kate Moss immediately after her drug scandal. I find her a great professional, and have always liked her personality. "I have never thought: 'Does this person use drugs or not?' I am anti-drugs, but what can you do? "As designers we have to trust the models' personality and professionalism. I don't want to know about their private lives."
