At just 21-years-old, Kylie Jenner has officially become the world's youngest billionaire, according to Forbes.
The magazine ranks the youngest of the Kardashian-Jenner family at number 2,057 out of 2,153 on this year's list of the world's richest people.
Her record-breaking feat is all thanks to her makeup empire -- Kylie Cosmetics.
She founded the company in 2015, launching the makeup giant with her lipstick and matching liner kits.
