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

"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."
