Britney Spears reportedly has turned down substantial amounts of cash to lose weight using several different companies' weight loss plans. Reports emerged last week that the companies wanted her as a spokesperson for their products. But now a report says Brit has turned to diet pills in order to drop those pounds.

Brit turns to diet pills?

Diet Pills?

That's how Star Magazine describes the pop tart's weight loss plan:

Desperate to rein in her ballooning weight, Brit, 24, has turned to a new diet-and-beauty pill that promises to curb her junk-food cravings, Star has learned exclusively.

Apparently unable to lose the extra 20 pounds she's gained since December, the 5'5" 140-lb. pop-star is currently negotiating to become the spokeswoman for NV, an all natural appetite suppressant developed in Canada that promises to help a person drop 35 pounds in six weeks.

"Britney is at her wit's end," a source close to the singer tells Star. "She wants to lose weight, but she's having the most difficult time doing it. Britney is feeling awful about herself right now."

Star also notes that reports that her hard-partying husband, Kevin Federline, 27, was cavorting with a dancer in Las Vegas on Dec. 5 haven't helped the situation. Nor has Kevin's general lack of support. "Kevin is not on board with Britney's diet and exercise plan," a source close to the pop-star tells the tabloid.

"She'll be lacing up her running shoes, getting ready for a long power walk on the beach outside their Malibu home, and Kevin will saunter into the bedroom and say, 'Hey, babe, let's go grab a bite.' And Britney can't resist."

If she indeed is going to try to lose weight with a product, she's making the right move by trying to get paid for the results.
