LATEST: Sir Paul McCartney's estranged wife Heather Mills has hit out at claims she worked as a high class prostitute before her marriage to the Beatles legend. The former model, who split from MCCartney in May (06), allegedly charged up to $8,000 (GBP4,400) for sex sessions in top London hotels with rich clients, including billionaire arms dealer ADNAN KHASHOGGI, according to Sunday tabloid, the News Of The World. However, the animal rights activist has furiously denied the charges, insisting she cleared her name in 2002 when similar accusations were made of her past. Her lawyers said in a statement: "Heather Mills MCCartney strongly denies the allegations in today's News of the World. "These are not new stories and were refuted by her lawyers four years ago when first raised. "The sources clearly are a variety of unreliable persons who have been paid for these stories. "The timing of the article is clearly designed to cause maximum hurt to Heather, her husband and family at this sensitive time."
