Paul McCartney and Heather Mills are today facing off in one of the biggest and most bitter divorce battles in showbusiness history today.
Sir Paul McCartney arriving at court this morning
The case, expected to last five days, is being heard behind closed doors in the family division of London's High Court.
Mills, the 40-year-old former model whose marriage to the pop icon lasted less than four years, is representing herself in court after sacking her lawyers.
Legal experts believe Mills is asking for up to €67 million from McCartney (65) and that he may be prepared to offer only half that sum. The former Beatle is worth an estimated €1.1 billion.
The case could set an important precedent in measuring just how much a spouse can pitch for when short marriages fail.
McCartney's lawyers argue he made the bulk of his millions before he met Mills. McCartney married Mills in 2002 four years after his first wife Linda died of cancer. They have a daughter, Beatrice (4).
Any settlement may be subject to a gagging order to keep secret the details of the agreement.
