Sir Paul McCartney and his estranged wife Heather Mills have spent 40 minutes alone together in a desperate attempt to end their bitter divorce battle amicably. The former beatle reportedly invited Mills into his US holiday home in East Hampton on Wednesday (30AUG06) after she picked up their three-year-old daughter BEATRICE. Shocked security guards were asked to leave the scene while the pair tried to resolve their differences. A source tells British newspaper the Sunday Mirror, "Paul and Heather have been doing their best to avoid each other for months. But they have decided to put their differences aside for the sake of their daughter."
