The tittle which was previously held by Facebook founder Mark Zuckerberg when he became a billionaire at age 23 has been snatched by the reality star.
The 21-year-old mother of one was officially given the title after months of speculations on Tuesday by Forbes as it unveiled its annual billionaires list.
Kylie, who is just 21-years-old is both the youngest self-made billionaire and the youngest billionaire on Forbes’ ‘young billionaires’ list.
Jenner has amassed a personal net worth of $1billion through her wildly successful range of make-up, Kylie Cosmetics.
She overtakes Zuckerberg, who was 23 when he made his first billion 11 years ago in 2008.
Now, he is the eighth richest person in the world with a fortune of $62.3billion.
Jenner is the youngest in her famous, reality TV family and the first to hit the billion dollar landmark.
She was surprised by the success of her cosmetics company, which was only founded in 2015 but is now worth an estimated $900million.
That’s a nice pat on the back.

‘I didn’t expect anything. I did not foresee the future. But the recognition feels really good.
‘That’s a nice pat on the back,’ Jenner told Forbes.
She credits her success to her enormous social media following, which ensured her customer base before she made her first product.
‘It’s the power of social media. I had such a strong reach before I was able to start anything,’ she said, adding that she sees the company going ‘very far’.
‘I see Kylie Cosmetics going very far. I work really hard,’ she said.
‘It’s always something that we’re willing to explore,’ she said.
