Kylie Jenner

In 2010, Kylie Jenner was a mere 12 years old. Even at such a young age, she was already a huge star in reality television, thanks to the hit TV show, Keeping Up with the Kardashians. Although she got some of the spotlight, being the youngest member of the family, she was still in the shadows of some of her older siblings.

Lucky for her, living in the shadows didn’t last long. In 2015, her life changed forever when she launched her company, Kylie Lip Kits. Fast forward a bit and her lip kits had grown into a full-fledged makeup company, Kylie Cosmetics, currently worth over $900 million. From being a young girl on reality TV, Kylie became the youngest self-made billionaire in history.
