Cornelia Guest, Daughter Of Fashion Icon, Goes Naked For New PETA Ad (PHOTO)

Cornelia Guest, the 47-year-old daughter of the late American actress and socialite C.Z. Guest, is the latest star to doff her duds to support PETA's anti-fur message, reports Women's Wear Daily.

In the new ads, Cornelia looks lovely with her hair in Lady Godiva-style blonde curls, posing next to PETA's famous slogan, "I'd Rather Go Naked Than Wear Fur."

But Cornelia didn't always shun fur. A PETA spokesperson told WWD that the organization embraces Guest for changing her attitudes about wearing animal products:

"Cornelia epitomizes elegance, privilege and sophistication. She represents a part of society that used to embrace fur. She is a great example of someone who has lived and learned," said Dan Mathews, senior vice president of campaigns for PETA.

Cornelia, who has served as a blogger for The Huffington Post, joins two other celebs who have recently stripped down for PETA: Canadian actress Laura Vandervoot and Angela Simmons. She's currently involved with a number of animal-friendly ventures, including a vegan handbag collection and a signature cookie label that helps benefit the Humane Society.

Guest's mother, born Lucy Douglas Cochrane, changed her name to C.Z. Guest when she married Winston Frederick Churchill Guest in 1947. Before her passing in 2003 of cancer, she wrote a gardening column for the Post and designed a line of sportswear, also once being named to the International Best Dressed List Hall of Fame.
