just randomly searching the Taschen books website i found this:

(kate moss by mario testino book)

Mario says “I met Kate very early on. Shortly after her first Galliano show I went backstage to congratulate her, only to find her crying: she was disappointed that she had only been given one outfit to model in the show. My answer to her was this: ‘In life there are perfumes and colognes. You need to use lots of cologne as the scent fades away; with a perfume you just use a drop and it lasts all night. You are a perfume, you will go on and on.’ Little did I know just how true that would become! And that I had made a friend for life.”

cheers
