Heather Mills has been photographed wearing a mink coat.The ardent animal rights campaigner - who branded former PETA supporter Naomi Campbell a "hypocrite" for sporting fur - is seen wearing a fur coat made from up to 40 animals in video footage filmed in 1989.The former model's sister-in-law Dianna Karmal told Britain's Daily Mirror newspaper: "She really loved that coat. When I see her anti-fur campaigns now, I always chuckle."It's laughable that she's called so many celebrities hypocrites. She's styled herself as an anti-fur campaigner but was proud to be in her mother's mink."The picture is from long ago but no-one's aware of her previous love of fur. The charities she campaigns for will all feel let down."Heather, who is currently involved in a bitter divorce battle with Sir Paul McCartney, was an active supporter of PETA but was dropped by the organisation earlier this year. It was claimed Paul's photographer daughter Mary threatened to stop working on the 'I would rather go naked than wear fur' campaign unless the animal rights group severed ties with her stepmother.Before Heather split from Paul last year, she regularly worked for PETA - protesting against Canadian seal culling and the fur trade.She even posed nude for PETA's 2007 calendar, but the photographs were dropped after her divorce battle began.
