Five years before she became a unipod and long before she got a leg up the social ladder by marrying a Beatle, Heather Mills did some porno modeling in a German book called Die Freuden Der Liebe (The Joys of Love). In the photos published in The Sun, she looks joyous, all right, and we can’t help thinking how her strenuous poses certainly required the use of two legs. We are also thinking that the existence of the book must have been known to at least a few people who kindly kept it under wraps until her breakup with the revered and venerated rock elder, Paul McCartney. Perhaps it was even Sir Paul himself who leaked the story? Anyway, Mills’ lawyers are denying she did anything unsavory or, God forbid, pornographic. “This photo shoot, undertaken approximately 20 years ago, was for the purpose of a ‘lovers guide’ to caring relationships and instructive sex in the same way as many other books on the market,” said the offices of Coyle White Devine. “The photo shoot was not pornographic or for the purposes of gratification of the viewer.” Because, as everyone knows, it wouldn’t occur to a man to gratify himself looking at a how-to sex book.
