Sir Paul McCartney's estranged wife Heather Mills claims she has received a number of death threats since she split with the ex-beatle in May (06). Mills also insists she cannot afford to hire security in the aftermath of her separation from MCCartney, which has turned increasingly ugly in recent weeks. The 38-year-old is the mother of MCCartney's three-year-old daughter BEATRICE. She says, "We've had a few death threats which is pretty scary. "We don't have any funding for security."
