Sir Paul McCartney's estranged wife Heather Mills was humiliated yesterday (07AUG06), when the rocker's security refused to let her into his London home, despite pre-arranging the visit. The former model, 38, brought the couple's two-year-old daughter BEATRICE to visit her father, but was dismayed to find the locks had been changed and the former beatle, 64, was not at home. Mills' security guard then attempted to scale the wall of the St John's Wood, north London mansion walls, which lead MCCartney's security to call police after believing there was an intruder attempting to break in. As police arrived, Mills drove her Mondeo car around the corner so her daughter would not be scared by the flashing lights of the patrol vehicle. After heated discussions with police and calls on her mobile phone, Mills was finally let into the home, where she spent the night, before leaving Beatrice with MCCartney today (08AUG06). A police spokesman confirmed, "We were called after a guard reported intruders. No arrests were made."
