Sir Paul McCartney has learned to be cautious after becoming a victim of phone-hacking - he refuses to hold long conversations over the phone and only leaves benign messages. The Beatles legend is convinced tabloid journalists commissioned a private investigator to improperly access his phone voicemail messages, and has agreed to talk to police investigating the headline-grabbing scandal. Sir Paul tells The Times he became wary in 2008 during his divorce from glamour model Heather Mills because there would be stories about how I was going on holiday to the Bahamas or whatever and I would know I hadnt told anyone. He adds, The worst thing is that then you suspect everyone - your PA (personal assistant), who you thought was a great girl - 'What if? At the time of the divorce, I realised there was quite a possibility of many people hacking me for various reasons. I used to talk on the phone and say, If youre taking this down, get a life. It is a pity not to be able to talk freely on a private call. ON
