Heather Mills is reportedly paranoid that she’s been spied on at all times and is worried that she’ll end up like Princess Diana, with whom she identifies strongly.

A source claimed to be a friend of Heather’s told the News of the World: “She has read every Diana biography out there. She feels she is misunderstood as a cold-hearted gold-digger, in the same way Diana was portrayed as being unstable.”

“And the fact she hired the same lawyers as Di is no coincidence either.”

“She’s convinced telephone calls are being bugged and keeps numerous mobiles to confuse people. She also thinks people are recording her conversations when she’s in restaurants.”

The newspaper also claimed Heather plans to claim estranged husband Paul McCartney has been drunk during visits with their daughter Beatrice and Heather will use that against him if he continues to challenge her for custody of the toddler.

A source close to Paul dismissed the allegation: “It sounds like when things don’t work she just makes something else up.”
