Guess Britney's Worth To The U.S. Economy

Ever get the feeling somebody is making a whole lot of money off Britney Spears besides Britney Spears?

Portfolio magazine estimates the annual value of Britney Spears to the U.S. economy is 110- to 120-million dollars -- and that's when she isn't even touring.

Portfolio estimates record companies, promoters and licensers make 30- to 40-million dollars because of endorsements, record sales and other business.

It estimates the paparazzi make 4 million dollars from selling photos of the Kentwood native. Celebrity tabloids, web traffic and other media make an estimated 75 million dollars off her in a year. A celebrity tabloid can sell as many as 33 percent more copies if Spears is on the cover.
