Surprised??  Yeah, me too.  Britney Spears has unleashed the POP PRINCESS POWER again, landing herself on top of the female earners in the music business.  I think this is quite cool.

The 31-year-old pop star hauled in $58 million over the past year thanks to her latest album, “Femme Fatale,” and the tour she did to support it.  Endorsement deals helped her bottom line.

Swift came in second on Forbes’ list at $57 million. The 22-year-old country crossover has been on a non-stop promo tour for her new album, “Red,” which went triple platinum in less than a month.
