Shares of Coty plummeted 13 percent on Friday after Forbes magazine kicked Kylie Jenner off it's billionaire's list and accused her of 'inflating the value of her cosmetics business for years.' Forbes published an article based on an examination of financial filings after the beauty mogul sold a majority share in her cosmetics company. Jenner sold a 51 percent stake in her Kylie Cosmetics brand to beauty giant Coty in January for $600 million in a deal that valued the company at $1.2 billion.
