Heather Mills, the estranged wife of Sir Paul McCartney, recently lost her PR adviser and has now officially parted ways with her divorce laywer. Mills, a former model before she lost a leg in a car accident, has been shooting off her mouth about her goings with Sir Paul and feeling like she’s on the brink of suicide. The result has been a steady thrashing of her by the British media. So she came to N. America to shoot off some more. Sir Paul is already seeing a new woman - the wife (?!!) of a lawyer and second cousin to Barbara Walters. But despite his trysts, kissing in cars and so on, he’s worried for the safety of his youngest daughter, Beatrice.
