Rihanna, 31 – $600 Million

No matter what she’s doing, Rihanna slays the game wherever she goes. Despite not having dropped a new album in a while, she’s still one of the most relevant artists out there thanks to her new business venture; her beauty brand Fenty Beauty.

Fenty has been a worldwide phenomenon, reportedly turning Rihanna into the world’s richest musician. Rihanna often does beauty tutorials featuring her products on YouTube, where she is completely unafraid to show her fresh face at the beginning of the videos in a series called Tutorial Tuesdays with Rihanna.
