NEW YORK (AFP) - Aged just 20 and the youngest member of the extended reality-TV Kardashian clan, Kylie Jenner is on track to become America's youngest "self-made" billionaire, Forbes has revealed.
The young mother, who gave birth to daughter Stormi in February, set up Kylie Cosmetics two years ago. It has already sold more than US$630 million (S$860 million) worth of make-up, the magazine said.
Forbes conservatively valued her company at US$800 million and raised her overall worth to US$900 million by throwing in earnings from television programmes, endorsements and after-tax dividends.
Jenner owns 100 per cent of the company.
She is already the youngest person on Forbes' list of richest self-made US women.
Another year of growth would make her the youngest self-made billionaire ever, beating Mr Mark Zuckerberg, who crossed the threshold at the age of 23.
"Thank you @Forbes for this article and the recognition. I'm so blessed to do what I love every day," she tweeted next to a photograph of the cover story.
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.
Forbes said the firm has only seven full-time and five part-time employees, with manufacturing, packaging and sales outsourced.
