At just 21 years old, Kylie Jenner has officially become the world's youngest self-made billionaire, according to Forbes.

Jenner has her own make-up brand, Kyle Cosmetics, and an estimated fortune of $1 billion.

Forbes said she’s considered self-made because she didn’t inherit the business or money.

Facebook's Mark Zuckerberg previously held the title, when he became a billionaire at 23 in 2008.

The top three richest people in the world are Jeff Bezos, Bill Gates and Warren Buffet.
