Rihanna
23
$29 million
Rihanna makes our list of the top earners under 30 in 10th place, although she just failed to make the cut for the Celebrity 100. The singer earned an estimated $29 million between May 2010 and May 2011 thanks to a tour, great album sales and endorsements with brands like Fuze Drinks and Venus Razors. She’s also becoming increasingly apt at attracting attention. Rihanna is the latest musician to kiss Brittney Spears at an awards show. The two locked lips at the recent Billboard Awards.
Beyoncé Knowles
29
$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.
