Heather Mills is set to accept almost 60 million cash and property divorce settlement from estranged husband Sir Paul McCartney.The former model has reportedly backtracked on her previous demands of $20,000 a day "just to get by". She is also said to have given up on her bid for sole custody of the couple's three-year-old daughter Beatrice. A source told Britain's News of the World newspaper: "It's amazing how quickly things have turned around. Heather has caved in on lots of things -including her money demands and the issue of sole custody. We now expect her to settle."Heather's stance has completely changed. Paul's legal team were worried she might have upped the stakes by threatening to leave England and take Beatrice with her. It could still take weeks to thrash out a deal but they're on the right path."The settlement is likely to include $50 million in cash and Paul's $8 million St John's Wood mansion in London. It is believed Paul, 64, has agreed to contribute $4 million towards Heather's security costs during the divorce proceedings. Despite apparently a settlement, Heather, 39, is allegedly planning to speakout about her four-year marriage to The Beatles legend.The source added: "Heather told me, 'I will not sign a gagging clause because I want people to know the truth.' "Leaked court documents from last year revealed Heather had claimed Paul was physically violent to her during their marriage. Her allegations included claims the musician had pushed her into a bath while she was pregnant and on another occasion stabbed her in the arm with a broken wine glass. Heather will take Beatrice to the US this week while she competes in TV show 'Dancing with the Stars'.
