LATEST: Sir Paul McCartney's estranged wife Heather Mills is shocked by reports she has been dropped by animal rights group People for the Ethical Treatment of Animals (PETA).
Mills and MCCartney have been animal welfare advocates for years and she was completely caught off guard by the news.
She tells US entertainment show EXTRA, "I was just shocked. I thought, 'Oh, God, what's this?'
She adds, "My girlfriend called me. That's how I first heard, and said, 'I'm really, really sorry to hear the bad news.'"
According to media reports, Mills was allegedly dumped after MCCartney's daughter MARY refused to shoot an ad campaign for the organisation unless they severed their ties with Mills.
Mills says she's hurt and disturbed that PETA has not officially informed her of their decision adding, "I fell really, really sad about it.
"They didn't send me a letter or call me up saying, 'We don't wish to work with you anymore.'"
Mills, who is currently involved in a bitter divorce battle with the former beatle, says she will continue to work for animal rights, with or without the organisation.
