Just when it seemed you couldn't possibly dig up another person to despise Paul McCartney's ex, Heather Mills, the lady's own publicist has just quit in a hilarious-and wordy-fit. Mills' former flack, Michele Elyzabeth, says the trouble started when Mills accused her of working on a tell-all book. "She was screaming and yelling, 'Is it true that you're writing a book about me?' I told her that it wasn't true, and she went bonkers... She was screaming so loud, she told whoever she was with to leave the room. She was yelling, 'I am tired of you, you're so stupid! You're so unprofessional.'"
