Beyonce, Britney, Gaga Make Forbes' 2010 Hollywood Moneymakers List

The R&B/pop star's estimated 2010 earnings of $87 million were enough to make her the highest-ranking musician on the list, at No. 9. Spears came in at No. 13 with $64 million netted over the past year, while Gaga closely followed at No. 14 with $62 million earned.

Other musical artists who made the bottom half of the list include Madonna (No. 15 with $58 million), Cyrus (No. 18 with $48 million) and Taylor Swift (No. 19 with $45 million). Oprah Winfrey easily snagged the top spot on the list with a whopping $315 million netted in 2010, while "Avatar" director James Cameron came in second with $210 million.

With Beyoncé earning $87 million in 2010, she and husband Jay-Z further prove their status as an unstoppable power couple. In August, the rapper topped Forbes' "Hip-Hop Cash Kings" list after making $63 million over a 12-month period.
