Supermodel Cindy Crawford has been labeled a “sell out” by animal rights group PETA (People for the Ethical Treatment of Animals). Crawford, 38, who once took part in PETA’s public campaign against the fur trade, and posed wearing a slogan “I’d rather go naked than wear fur,” has signed up to appear in fur giant’s Blackglama ad campaign later this year.

A group of PETA protesters gathered outside Whiskey bar owned by supermodel’s husband’s Rande Gerber, brandishing posters with Crawford’s anti-fur pictures, emblazoned with the word “Sell Out”.

"When the Whiskey's patrons see how animals suffer in the fur trade, they're going to need a stiff drink," said Dan Mathews, Vice President of PETA group.

"This week, while you're busy airbrushing your pictures, we're compiling horrific video footage of a fur farm in Michigan that we recently investigated, which shows chinchillas struggling and screaming as they're plugged into a wall socket and electrocuted for their pelts," reads the letter Mathews sent to Crawford.

PETA has often slammed fur-wearing celebrities, such as Martha Stewart and Diana Ross. The group has considered supermodels turn to lucrative fur contracts as betrayal and wants to draw the public’s attention to her change of ethics.

However, Crawford’s publicist Annet Wolf has been fiercely defending the supermodel.

"This is so unfair," she told the New York Times. "She's not pretending to be anything she isn't. It's so outrageous… Cindy was never a PETA spokesperson nor has she taken a stand against fur. She was never in a PETA campaign. All she did was one photo as a favor to Todd Oldham."
