Forbes says Kylie Jenner is not a billionaire an investigation found, adding the Kardashian-Jenner family provided misleading information.

Kylie Jenner's status as a billionaire has been called into question by Forbes in a story that also raises questions about the magazine’s ability to accurately assess the finances of celebrities.

Forbes, known for its billionaire rankings, said it no longer considers the youngest member of the Kardashian-Jenner family to be a billionaire, which it reported in March 2019.

The magazine on Friday published the results of an investigation into Jenner's finances, saying she and her family provided misleading information about her wealth.

'Unproven assumptions': Kylie Jenner responds to Forbes report on 'inflating' billionaire status.

Forbes called the sale one of "the greatest celebrity cashouts of all time" and said "the transaction seemed to confirm what Kylie had been saying all along" and what it declared in the March 2019 story. Coty officials declined to comment

Jenner pocketed an estimated $340 million, after tax, from the sale, Forbes reported but said based on filings and the impact of COVID-19 on beauty stocks and consumer spending that Jenner is not believed to be a billionaire

Forbes also said in its story that the family created "tax returns that were likely forged," which Jenner’s attorney Michael Kump said was "unequivocally false" in a statement to People magazine

With the success of her cosmetics line, Kylie Cosmetics, Kylie Jenner has officially surpassed Mark Zuckerberg as the youngest self-made billionaire by the age of 21, according to Forbes

Rita McGrath, who is professor of management at Columbia Business School, said the story puts Forbes in a "tough spot."

Vega said Forbes' "investigation was triggered by newly-filed documents that revealed glaring discrepancies between information privately supplied to journalists and information publicly supplied to shareholders."
