8. Beyonce Knowles
Age: 29*
2010-2011 Income: $35 Million

The Houston-born diva ranks unusually low on our list because she didn’t tour or release an album over the past year. But her fourth solo effort, 4, is on the way. The simple title was reportedly selected by her fans, and is also a nod to her April 4 wedding anniversary with hubby Jay-Z. In the absence of new revenue on the music side, business-focused Beyoncé cashes in on clothing line Dereon and endorsement deals with L’Oréal, DirecTV, General Mills and others.
