Music legend Sir Paul McCartney will celebrate his landmark 65th birthday with estranged wife Heather Mills and their daughter BEATRICE, according to reports. The former Beatle called a truce with Mills for the sake of their three-year-old daughter following their split a year ago (May06). According to British magazine Hello!, Mills will not attend the official birthday party on 18 June (07) but will mark the event with MCCartney privately. A source says, "She's not going to his party, because she feels that is inappropriate and would cause too much ill feeling among the family. "But Paul, Heather and Bea will have a special celebration with cake and presents. Their celebration will take place on the day of his birthday and Heather will buy a present from Bea, but also one from herself."
