Pop star Rihanna has been named the world's richest female musician by Forbes, but her fortune isn't solely from her music.

The Barbadian singer and entrepreneur has amassed an estimated fortune of about $600 million through her music and Fenty Beauty makeup business, which she runs in tandem with her singing career.

Forbes magazine reports that the popular Fenty line made $100 million in its first few weeks.

Rihanna worth a fortune of about $600 million

The 31-year-old has surpassed music icons Madonna ($570 million), Celine Dion ($450 million) and Beyoncé ($400 million).

As well as her music career and cosmetics, Rihanna, full name Robyn Rihanna Fenty, has also launched the Savage X Fenty lingerie line.

She is also set to become the first black woman in charge of a major luxury fashion house when she launches her new fashion label at French luxury goods company LVMH, which owns Louis Vuitton.

Her fortune is down to her cosmetics and clothing lines and music career

In an interview with The New York Times last month, Rihanna said money was not her main motivation.

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

"Work will change when my life changes in the future, but an amount of money is not going to stop that."

Earlier this week Forbes named rapper Jay-Z as the first hip-hop star to become a billionaire, crediting his wealth to his music career and varied business interests in fashion, alcohol and the transport app Uber.
