Kylie is the youngest member of the Kardashian-Jenner family. And she’s also the richest.

So, how did Kylie Jenner make money?

The 21-year-old has a net worth of $900 million – which is more than her very famous sister, Kim Kardashian West (est. $350m).

She made it onto the cover of Forbes magazine this year as the youngest ever self-made billionaire.

Kylie Cosmetics

In 2016, Kylie launched a make-up brand called Kylie Cosmetics.

The brand began by selling $29 lip kits which consisted of a lipstick and a matching lip liner.

Since 2016 the cosmetics brand has truly skyrocketed.

As a result, it has now expanded to other makeup products including eyeshadow palettes, highlighter and concealer.

SAY NO MORE Velvet Lip Kit 💕

Kylie Jenner Flashes the Cash

It seems that the youngest member of the Kardashian-Jenner clan isn’t afraid to show off what her business sense has earned her.

Kylie and her sister, Kim Kardashian West, just bought matching neon Mercedes trucks.

Totally casual, we know…

Kylie definitely likes to post her lavish lifestyle on Instagram.

Some posts are even rumoured to make a million dollars each time.

Kylie’s success keeps going from strength to strength and she’s only just turned 21!

So, she can certainly celebrate her achievements so far this year. Let’s face it, she’s raking in the cash and now has an adorable family of her own.

It seems with a momager like Kris Jenner, it never could’ve gone that wrong. But even still, $900m, that’s an impressive net worth!
