Forbes estimated that Jenner's Kylie Cosmetics is worth at least $900 million (USD), and she owns it all. The magazine said she hits the billion-dollar mark when adding the cash she has already pulled-in from the profitable business.

Facebook's Zuckerberg was 23 when he hit the big B mark.

Jenner told Forbes the milestone is a "nice pat on the back."
