Shocking behind-the-scenes secrets of Sex And The City are poised for exposure in a new tell-all book.

Another revelation set to be published tells how executive producer Darren Star allegedly turned down Hollywood actor Ashton Kutcher for a part in the show, stating , "I don't see this kid going anywhere'.
