LOS ANGELES • Forbes magazine, which in March last year declared that reality TV star Kylie Jenner had become the world's youngest self-made billionaire, said on Friday that it no longer believed that her net worth was that much.

The magazine said it reviewed financial data released by beauty conglomerate Coty, which bought a 51 per cent stake in Jenner's Kylie Cosmetics company in November last year.

Those financial filings show that "Kylie's business is significantly smaller, and less profitable, than the family has spent years leading the cosmetics industry and media outlets, including Forbes, to believe", the magazine said.

Forbes now estimates the net worth of Jenner, 22, at around US$900 million (S$1.27 billion).

Writing on Twitter on Friday, Jenner said that the recent story was based on "a number of inaccurate statements and unproven assumptions".

"What am I even waking up to. I thought this was a reputable site," she wrote.

Jenner, half-sister of Kim, Khloe and Kourtney Kardashian, debuted Kylie Cosmetics in 2016 with US$29 lip kits containing matching lipstick and lip liner.

She first grabbed the spotlight in reality TV show Keeping Up With The Kardashians, which she starred in with her mother and siblings.

In her Twitter postings on Friday, Jenner said she was "blessed beyond my years, I have a beautiful daughter, and a successful business and I'm doing perfectly fine".

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