Kylie Jenner is 25 years old — and she's worth $600 million. Take a look at how the mogul built her empire.

• In March 2019, Forbes dubbed then 21-year-old Kylie Jenner the world's youngest "self-made" billionaire.
• The magazine later admitted Jenner had exaggerated the size of her business and pegged her true net worth at $600 million.
• Here's how Jenner has made her millions, from Kylie Cosmetics to TV appearances to product endorsements.

Kylie Jenner, the ever controversial reality star, is 25 years old. She's most likely spending it in style, whether that's renting a $200 million superyacht or taking quick trips on her $73 million private jet. 

Forbes previously declared Jenner the world's youngest "self-made" billionaire at age 21, thanks to her makeup company, Kylie Cosmetics. But in a May 2020 investigation, Forbes went on to report that Jenner is not, in fact, a billionaire. The magazine said that Jenner has exaggerated the size and profitability of her business and misled Forbes and other publications since 2016.

Jenner founded Kylie Cosmetics in 2015 and claimed to have brought in $400 million in revenue in its first 18 months, per Forbes. In November 2019, Jenner signed a deal to sell a majority stake in her cosmetics company to beauty conglomerate Coty Inc. for $600 million, which valued the company at $1.2 billion. 

But Forbes alleged that the company has never made as much money as the Jenners claimed, and that her business has suffered during the coronavirus pandemic. A representative for Jenner did not respond to Business Insider's request for comment.

Despite her disputed billionaire status, Jenner has amassed a cosmetics empire, starred alongside her family in "Keeping Up with the Kardashians" as well as in her own spin-off show "Life of Kylie," started a clothing line with her sister, and made millions promoting products on Instagram.

Here are all the ways Jenner has made her millions.
