Kylie Jenner, youngest self-made billionaire?

Kylie Jenner, 20, is on the track to become America's youngest "self-made" billionaire. The youngest member of the reality TV stars Kardashian clan is worth $900 million at least.

According to Forbes magazine, Kylie Cosmetics, the company that Kylie established two years ago, has already sold more than $630 million worth of makeup. Forbes conservatively valued her company at $800 million and raised her overall worth to $900 million by throwing in earnings from television programs, endorsements and after-tax dividends.

The model owns 100% of the company, which started out with a $29 "lip kit" – matching set of lipstick and lip liner that traded on her trademark pout.

She is already the youngest person on Forbes' 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.

Kylie tweeted next to a photograph of the cover story: "Thank you @Forbes for this article and the recognition. I'm so blessed to do what I love every day." 

Her success has been attributed to her fame and ability to leverage social media. She has more than 110 million followers on Instagram, 25.6 million on Twitter and 16.4 million follow her company directly.

Kylie Jenner is the youngest daughter of Kris and Caitlyn, formerly Olympic gold medallist Bruce. Her sister is supermodel Kendall. Her half-sisters are Kim, Kourtney, and Khloe Kardashian.

Reality TV show "Keeping Up With the Kardashians" launched when Kylie was 10 years old.
