She's done it: Kylie Jenner is the youngest self-made billionaire ever at 21. Perhaps better known for her role in reality TV's Keeping Up With the Kardashians, Jenner is the sole owner of Kylie Cosmetics, which launched in 2016 and is now valued at $900 million. "Add in the cash Jenner has already pulled from the profitable business, and the 21-year-old is now a billionaire, with an estimated fortune of $1 billion," according to Forbes, which ranks her as the world's 2,057th richest person.
"[The recognition] feels really good," Jenner tells the magazine, which notes Mark Zuckerberg didn't become a billionaire until age 23. Jenner credits much of her brand's success to social media, where she has more than 175 million followers across all platforms. Per the Guardian, her business, with just 12 full- or part-time employees, is "almost totally outsourced." It made $360 million in sales last year. ("Momager" Kris Jenner helps out, too.)
