Forbes names Rihanna the world's richest female musician

With 72 million followers on Instagram alone, Rihanna never has to market the many products, such as her popular, inclusive makeup brand Fenty Beauty, in the traditional, often more expensive way. The singer and beauty mogul just needs to snap a photo or add a hashtag to attract eyeballs.

Rihanna’s low-cost marketing strategy — the same one used by Kylie Jenner — has helped her to amass a $600 million fortune and become the world’s richest female musician, according to Forbes.

Madonna ($570 million), Celine Dion ($450 million) and Beyoncé ($400 million) were runners-up on the annual list.
