Lagerfeld was a supporter of the use of fur in fashion, although he himself did not wear fur and hardly ate meat. In a BBC interview in 2009, he claimed that hunters "make a living having learnt nothing else than hunting, killing those beasts who would kill us if they could" and maintained: "In a meat-eating world, wearing leather for shoes and clothes and even handbags, the discussion of fur is childish." Spokespersons for People for the Ethical Treatment of Animals (PETA) called Lagerfeld "a fashion dinosaur who is as out of step as his furs are out of style", and "particularly delusional with his kill-or-be-killed mentality. When was the last time a person's life was threatened by a mink or rabbit?" In 2001, he was the target of a pieing at a fashion premiere at Lincoln Center in New York City. However, the tofu pies hurled by animal rights activists in protest against his use of fur within his collections went astray, instead hitting Calvin Klein. A PETA spokesperson described the hit on Klein as "friendly fire", calling Klein, who does not use fur, "a great friend to the animals" and Lagerfeld a "designer dinosaur", who continues to use fur in his collections. In 2010, after Lagerfeld used fake fur in his 2010 Chanel collection, PETA's website claimed: "It's the triumph of fake fur ... because fake fur changed so much and became so great now that you can hardly see a difference".
Lagerfeld in 2009 joined critics of supermodel Heidi Klum, following German designer Wolfgang Joop's remarks about Klum, who had posed naked on the cover of the German edition of GQ magazine. Joop described Klum as being "no runway model. She is simply too heavy and has too big a bust". Lagerfeld commented that neither he nor Claudia Schiffer knew Klum, as she had never worked in Paris, and that she was insignificant in the world of high fashion, being "more bling bling and glamorous than current fashion". He created an international furore on 9 February 2012, when he called the singer Adele "a little too fat." Adele responded that she is like the majority of women, and she is very proud of that fact. Lagerfeld later caused another controversy, on 31 July 2012, when he criticised Pippa Middleton, the sister of Kate Middleton, for her looks.
