The 22-year-old model, the spitting image of her mother, posed nude for PETA, known for its hardline anti-fur stance and some-would-say militant veganism.
"So thrilled to share my brand new Rather Go Naked Than Wear Fur campaign with @peta!" she wrote in an Instagram caption.
"I've dreamt of shooting this for as long as I can remember. If you don’t truly know what goes into making fur, please educate yourself."
She follows in the footsteps of her famous mother, who posed for PETA back in the day.
"Fur is cruel no matter what. If you wouldn’t skin and wear your own dog, then you shouldn’t wear fur at all because all animals are created equal," she added.
"Save our animals, save our planet and join me and #Peta in making more conscious choices."
