Beyonce & Mariah Carey Crowned "Cash Queens"

Music's female stars are raking in cash by the millions, prompting Forbes magazine to crown 20 chanteuses, including Beyoncé and Mariah Carey in its list of "Cash Queens."

Though Forbes has previously generated a list of the top female earners in entertainment, for this list of "Cash Queens," the publication narrowed its focus to female singers; calculating concert grosses, merchandising revenue, album sales and revenue from clothing lines, fragrance deals and endorsements for artists who either toured or released an album or film between June 2006 and June 2007. The result was a combined $420 million in gross income earnings.

While B didn't top the list, along with Gwen Stefani and Christina Aguilera she landed in the top 10--#5, #6, and #7 respectively. Beyoncé banked $27 million, raking in revenue from deals with L'Oreal, American Express and Samsung, while Gwen Stefani's L.A.M.B. line helped push her profits to $26 million and Aguilera's partnership with Pepsi helped her put $20 million in the bank.

Madonna led the pack by pulling in $72 million thanks to income from record sales, a deal with H&M and her record-breaking "Confessions" tour, which grossed $260 million worldwide. The money is expected to keep on coming for Madge, who recently left Warner Music Group for a 10-year deal with Live Nation worth approximately $120 million.

Longtime favorite Mariah Carey won the #10 spot with $13 million in earnings, followed closely by 20-year-old Hilary Duff, the youngest to land on Forbes list, with $12 million thanks primarily to merchandising stemming from her stint as Disney's Lizzie McGuire. Despite her troubled year, Britney Spears profited $8 million, trailed closely by Nelly Furtado ($7 million) and Jennifer Lopez ($6 million).

In related news, Rihanna and Raven Symone recently earned spots on the "Ten Most Powerful Girls" list in the new issue of US Magazine, which treads similar territory to Forbes' list. Raven reportedly made $400 million from her Disney show "That's So Raven." In addition to star power and earnings the US list cites Rihanna and Symone for their qualities as role models.
