Kylie Jenner, the ever controversial reality star, just turned 23 years old. She's most likely spending it in style — last year she rented a $200 million superyacht to celebrate.

Forbes declared Jenner the world's youngest "self-made" billionaire at age 21, thanks to her makeup company, Kylie Cosmetics. But in a May 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 alleges that the company has never made as much money as the Jenners claimed, and also 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.

At the time, Forbes estimated that Jenner's company, Kylie Cosmetics, was worth $900 million.

That plus her personal earnings from the company brought her net worth to more than $1 billion, Forbes said.

Many criticized Forbes' decision to call Jenner "self-made," saying she was born into wealth and privilege. Jenner responded to the backlash in an interview with Paper magazine, saying, "The self-made thing is true" and adding that her parents "cut her off at the age of 15." 

While Forbes reported that Jenner was still the youngest "self-made" billionaire in the world on April 7, a more recent Forbes report released in May contended that the 22-year-old is not, in fact, a billionaire. Per Forbes' new investigation, Jenner and her mother and marketing manager, Kris Jenner, have exaggerated the size and profitability of her business and misled Forbes and other publications since 2016.

But Forbes concedes that Jenner is still a multimillionaire, now pegging her true net worth at $900 million.

At the time, Jenner took to Twitter to slam Forbes' report. "I thought this was a reputable site... all I see are a number of inaccurate statements and unproven assumptions lol. I've never asked for any title or tried to lie my way there EVER. period," she tweeted, also questioning Forbes' "proof" of the claim that tax returns "were likely forged."

"I can name a list of 100 things more important right now than fixating on how much money I have," Jenner tweeted.
