Kylie Jenner has been named the youngest self-made billionaire of all time by Forbes magazine. This is mostly thanks to the booming cosmetics company she founded three years ago.

According to Forbes, the 21 year-old half-sister of reality TV stars Kim, Khloe and Kourtney Kardashian is both the world’s youngest billionaire and also the youngest self-made billionaire ever.

She made it onto the annual Forbes list of billionaires after debuting her Kylie Cosmetics online in 2015 with $29 lip kits containing matching lipstick and lip liner.

The richest person in the world remains Amazon founder Jeff Bezos, with Microsoft co-founder Bill Gates remaining in the No. 2 position.
