Buzzfeed news reports Kylie Jenner is on track to be the youngest ever self-made billionaire. The 20-year-old makeup mogul is on the cover of Forbes magazine this month, which claims that she has amassed $900 million in three years from Kylie Cosmetics. Jenner owns 100% of the company, according to the magazine. Forbes says Kylie’s net worth will likely pass $1 billion within the next year. Some people are very salty about this.
