Love her or hate her, there's no denying that Kylie Jenner is a force to be reckoned with. And now the most junior member of the Kardashian clan is set to become the youngest self-made billionaire in the United States, according to <em>Forbes</em> magazine, which has put the reality TV star on its August 31 cover. This is largely thanks to her company Kylie Cosmetics, which she launched two years ago, selling $29 lip kits containing matching lipstick and lip liners. She has since sold more than $630 million worth of make-up and the Kylie Cosmetics range has grown to include eyeshadow palettes, eyeliners, concealers, blushes and highlighters (dubbed, in this case, Kylighters). The 20-year-old owns 100 per cent of her company, which Forbes conservatively valued at $800 million, raising her overall worth to $900 million by throwing in earnings from television programmes, endorsements and after-tax dividends. Forbes said that she used $250,000 earned from modelling to pay a company to produce the first 15,000 lip kits. They sold out in less than a minute at the November 2015 launch. She's already the youngest person on <em>Forbes</em>' list of richest self-made US women and another year of growth would make her the youngest self-made billionaire ever, beating Mark Zuckerberg, who crossed the threshold at the age of 23. Controversially for someone selling the perfect pout, Jenner has admitted to having temporary lip fillers but, earlier this week, she revealed that she had ditched them. Jenner posted a picture of her Forbes cover on Instagram, with the message: “Thank you for this article and the recognition. I’m so blessed to do what I do every day. I couldn’t have dreamt this up.” The entrepreneur, who has 110 million followers on Instagram and 25.6 million on Twitter, also gave birth to a daughter, Stormi, in February. <strong>_____________________</strong> <strong>Read more:</strong> <strong>_____________________</strong>
