Rihanna
R&B beauty Rihanna is on course to become one of the world's wealthiest young pop stars - she earned a massive $15 million (£10 million) in 2008.
The Umbrella hitmaker is reported to have made most of her money from her third album, 2007's Good Girl Gone Bad, as well as her various tours and endorsement deals.
Forbes magazine claims the 21 year old also profited from the re-release of her hit album, which was re-issued with added tracks and remixes last year, and her contract with fashion giant Gucci.
R&B superstar Beyonce is currently the wealthiest celebrity under the age of 30, earning a staggering $87 million (£58 million) in the last year.
