'Forbes' has released their annual World’s Billionaire List, and guess who was featured for the second year in a row? Kylie Jenner, of course. Jenner is still the youngest self-made billionaire on their list, despite the fact she faced backlash last year for the title. Jenner, who is only 22-years old is reportedly worth $1 billion after building a beauty empire known as 'Kylie Cosmetics'. Last year, Forbes declared Jenner to be the world’s youngest self-made billionaire, but then her net worth only increased as Jenner sold 51% of Kylie Cosmetics to Coty Inc., for $600 million.
