Lil Wayne

Age: 29

Pay: $27 million

Thanks partly to his new album Carter IV, 2012 has been a particularly lucrative year for pint-sized rapper Lil Wayne. The record sold 1 million copies in its first week of release, but the majority of his earnings have come from touring, having played 50 shows in the last year which grossed $600,000 a night. With the launch of his clothing line and his first big endorsement deal thrown into the mix, it's expected the star's fortune will only grow.
