Rihanna has been named the world’s richest female musician, with an estimated fortune of $600 million.

According to Forbes magazine, the singer makes the majority of her money from touring and musical releases, as well as from her fashion brand "Fenty".

"I never thought I'd make this much money, so a number is not going to stop me from working," she told The New York Times' T Magazine in May.

"Money is happening along the way, but I'm working out of what I love to do, what I'm passionate about."
