They couldn't work it out after all.

After a week of private hearings, Sir Paul McCartney and estranged wife Heather Mills have not been able to reach a divorce settlement. A judge will now impose a decision on the couple's final outcome, according to one of the ex-Beatle's lawyers.

Nicholas Mostyn, who has been representing the 65-year-old rock legend, confirmed with reporters outside London's High Court on February 18 that judge Hugh Bennett would rule on the case several weeks from now, according to AFP.

Either side will be able to appeal Bennett's decision should they disagree with it, but this would bring the case to the public. Up to now, McCartney's and Mills' sides have been negotiating behind closed doors. If the spouses accept the outcome, it will remain private, unless the pair permits public coverage of it.

Since their separation in May 2006, McCartney and Mills have been thrashing it out over how much Mills, 40, should get from his fortune. McCartney's financial worth has been estimated to be around 825 million pounds (the equivalent of $1.6 billion U.S.). Some media have reported that the former "Cute Beatle" has offered her 55 million pounds, but that Mills refused it. The Daily Mail has said that she would only accept a 20-million-pound lump sum plus another 2.5 million a year until the couple's daughter, Beatrice, turns 18.

The final decision, should the couple not appeal it, may well be Britain's largest-ever divorce settlement.

Mills represented herself in last week's court hearings; she had a falling out with her lawyers in the fall. McCartney's legal team includes Fiona Shackleton, who once represented Prince Charles in his divorce.

So will McCartney and Mills finally be able to Let It Be? Let's hope so, for Beatrice's sake. In the meantime, read this article to increase your self-awareness about your personal relationship with money.
