Net worth: $72 million

Rihanna has sold more than 20 million albums and 60 million singles, which makes her one of the best selling artists of all time. She made $29 million last year, which put her on “Forbes’ 25 Highest Paid Musicians” list in 2010. That same year, she released a book called “Rihanna” (how fitting), and she’s currently a celebrity spokesperson for several companies, including COVERGIRL and Nivea.

According to “People,” she likes to splurge on makeup and shoes, especially Louboutins. And earlier this year, the “New York Post” reported that she spent $1,500 on lingerie, candles, and handcuffs in a London sex shop.
