Kylie Jenner: Reality TV Star and Businesswoman

Aged only 21, Kylie Jenner became the youngest-ever self-made billionaire on the Forbes list, thanks to her company, Kylie Cosmetics. She founded this company in 2015, with the release of the Kylie Lip Kit, comprising a liquid lipstick and a lip liner. 

The company has expanded dramatically. In November 2019, fragrance and cosmetics giant Coty Inc. bought a majority stake of 51% for $600 billion. Jenner also has a strong social media presence with 163 million followers.
