London, July 26 : French-born PR guru Michele Elyzabeth has ended her association with Heather Mills' as her publicist, calling the latter "an impossible person".
Elyzabeth, who had fiercely defended Heather in the US for four years, said that she had decided to "cease representing" Mills because she could not stand her outbursts any more.
Mills' calling Elyzabeth stupid was the final straw, say reports.
"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," British tabloid The Sun quoted her as saying.
"Since her divorce has become final Heather has become an impossible person," she added.
Elyzabeth's leaving Mills comes after the latter ditched lawyers Mishcon de Reya during her divorce battle with Sir Paul McCartney, and her British PR adviser Phil Hall stepped down when she ignored his advice.
