In 1979, a penniless performer in Nu Yawk stripped off for a photographer in order to pay her way through dance school. Six years later when the dancer had become a household name, the "intimate" photographs turned up in Playboy magazine. It is so seedily to type it could be the plotline of a schmaltzy rags-to-riches movie, but of course we are talking about the one and only pop diva Madonna. Martin Schreiber was the photography teacher at Parsons School at the time of Madonna's undressing, and Miss Ciccone was a 20-year-old student. Now we all have the opportunity to see these notorious images as they're in an exhibition to coincide with her new tour starting on 4 July. Lets just hope they are not sticky or, er, sweet.
