Move over, Kim Kardashian. Your famous rear end may have some competition – from your little sister.

In a new anti-fur ad for PETA, Keeping Up with the Kardashians costar Khloe Kardashian disrobes and shows off her posterior. Next to the star, 24, is the tagline “Fur? I d Rather Go Naked.”

Even so, publicly displaying her caboose may be easier than convincing her sister to stop wearing fur.

“Kim wore fur last night,” Khloe told E! Online at Wednesday’s unveiling of her ad. “I told her you cannot wear fur. It’s embarrassing.”
