Kate 'betrayed for £750,000'

Kate Moss's agent has spoken for the first time about the model's drug-taking.

Sarah Doukas, who has looked after Moss for the past 18 years, said she was horrified when she saw the pictures of her biggest client snorting cocaine.

"Kate was absolutely devastated. I read it over the phone and the avalanche started immediately," she said.

Doukas, managing director of top model agency Storm, said despite rumours of drug-taking she never probed Moss about her private life.

"I've never seen that side of her. She's always gone to work every day. You couldn't sustain an excruciating schedule if there was a problem." And despite helping Moss draft last week's public apology, Doukas denies that Moss has a cocaine problem.

However, she admitted things got worse when "vulnerable" Moss started dating Babyshambles singer and known drug user, Pete Doherty. The newspaper pictures of Moss taking cocaine were taken on a mobile phone during an allnight binge with Doherty.

Doukas is furious someone made £750,000 by betraying Moss, whom she described as a fantastic mother.
