Move over Mark Zuckerberg, Kylie Jenner's officially the youngest BILLIONAIRE ever!

Kylie Jenner is officially the youngest self-made billionaire of all time, snatching the title from Facebook founder Mark Zuckerberg.

Jenner, 21, was finally given the title after months of speculation on Tuesday by Forbes as it unveiled its annual billionaires list. At 21, she 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.
