Britney Spears is so furious over rumours she takes diet pills, she's threatening to sue drug companies who are using her to sell their products.

Earlier this year (03) the 21-year-old was spotted at London's HEATHROW AIRPORT picking up a blue bottle of what newspapers claimed was popular diet pills ZANTREX-3.

Now, some internet sites are selling the appetite suppressing "fat burner" by claiming "pop princess Britney Spears maintains her sexy shape with Zantrex-3".

But Britney is said to be outraged by the claims.

Her lawyer insists the blonde beauty "does not endorse" the diet product and "any company using a photo of her inappropriately" will be contacted and told to "remove the photo".
