Is Kim Kardashian teasing Kylie Jenner about her billionaire status? Is she bragging that she’s a billionaire and Kylie isn’t? Forbes left Kylie Jenner’s fans in shock when they rescinded their declaration that she was the youngest billionaire in history and alleged that she misrepresented her earnings on tax documents. Now, Kanye West declared his wife Kim Kardashian a billionaire, and once again, Forbes turned around and declared that Kim Kardashian isn’t really a billionaire either.
