The 34-year-old singer and fashion mogul ranks 21st overall on Forbes’ annual list of America’s richest self-made women. She’s also the only billionaire under 40 on the list.
At 41, Kim is older but has more money. The reality star is worth $1.8 billion, while Rihanna’s net worth is $1.4 billion
Kylie Jenner — who is the youngest non-billionaire on the list at age 24 — was named Forbes’ youngest self-made billionaire in 2018, but that title was taken away when it turned out she was worth 'only" $600 million.
Most of Rihanna’s money comes from her companies Fenty Beauty and Savage X Fenty. She hasn't dropped an album since 2016.
