Stella McCartney angry over Madonna's fur coat

Madonna has landed in trouble with designer friend Stella McCartney for wearing a coat made out of lamb foetuses.

Dedicated anti-fur campaigner McCartney said she was appalled when she spotted the singer wearing it.

Animal rights activists claim lambskin uses the pelts of unborn karakul lambs and the daughter of former Beatle Sir Paul wasted no time telling Madonna the gory facts.

She told Glamour magazine: “I’ve been working on Madonna’s honky ass for a very long time. Her thing is she won’t wear anything she doesn’t eat.

“But the other day she was wearing this lamb foetus coat, made from baby lambs that haven’t even been born.

“It’s like wet curls. So I said, ‘I didn’t know you ate foetuses,’ and she was like, ‘Eeew!’ I haven’t seen her in it since.”

Madonna incurred the wrath of animal rights protesters last year when she wore a £1,000 fox fur hat by Philip Treacy.

McCartney, who has narrated a video for People for the Ethical Treatment of Animals (PETA), also has a go at another of her celebrity friends, actress Gwyneth Paltrow.

She said: “The only time I’ve seen Gwyneth with fur she’s had a little trim on her coat and I’m always like, ‘What the f**k are you doing with that?’

“And she’s like, ‘It’s not real fur’ and I say, ‘Don’t give me that shit, you’re a clever girl – don’t try and act like a stupid girl right now’.

“The last time, she guaranteed she wasn’t going to do it again, but they’re all a bit fickle, aren’t they?”

She adds: “Listen, I love her, but on the fur thing, people really are very fickle.”

McCartney is planning to marry boyfriend Alasdhair Willis next year and will be designing her own dress.

“I’ll probably change the design every three seconds. But I just can’t think of anyone else to do it,” she said.
