Claims that Sir Paul McCartney's estranged wife Heather Mills was once a highly paid escort have come to the fore again after arms dealing tycoon ADNAN KHASHOGGI refuses to deny his links to the former model in a new TV interview. In an upcoming US interview for TV show The Insider, the Turkish businessman is asked if he ever paid Mills for sex and he's defiant in his answer. He says, "Even if she was a prostitute, what's the big deal?" Mills has always denied the allegations she offered sex for money to high-powered businessmen. He spokesperson repeats, "She does not want to comment on any media speculation at this time."
