Ex-Publicist Agrees With British Press About Heather Mills

Heather Mills' former publicist has spoken out against her former employer, saying she agrees with the British media's low opinion of Paul McCartney's ex-wife.

"After working for Heather Mills for the past four years, I have decided to cease representing her," Michele Elyzabeth said in a statement to "Extra."

"Since her divorce has become final, in my opinion, Heather has become an impossible person. Yesterday, we engaged in a heated argument during which she called me 'stupid.' I reminded her that she was not 'God' and she answered, 'I will never ever talk to you again.'"

Elyzabeth adds that she has been "very patient" with Mills, but "cannot take anymore."

"I have given her substantial unpaid time and attention. I am owed money. I refuse to be subjected to her outbursts. On reflection and given the way I have been treated, I now have sympathy with much of what the British Press has reported about her."

Mills, 40, emerged from the bitter divorce with a settlement of $47.5 million and custody of the couple's 4-year-old daughter, Beatrice. McCartney, 66, retained the bulk of his fortune, estimated at $880 million.

McCartney married Mills, whose left leg was amputated below the knee after a 1993 motorcycle accident, in an Irish castle in 2002. They separated four years later.
