Pop-singer Britney Spears is suing eight insurance companies who refused to pay her a nearly 10-million claim for her knee injury resulting in a cancellation of her 2004 summer tour. Britney hurt her knee during the shooting of her “Outrageous” video last year. The pop-princess was getting ready to tour United States, Europe and Canada, but had to cancel her 82-day Onyx Hotel Tour and undergo arthroscopic surgery.

The insurance companies rejected the singer’s $9,8 million claim on the grounds that she had not mentioned a knee surgery that she underwent in 1999. According to the insurance companies, Britney Spears already had a pre-existing condition for her injury in 2004.

In a lawsuit, filed in Manhattan Supreme Court last week, Britney Spears claims that not mentioning her 1999 “minor” surgery was an “innocent omission” not connected to the accident at the shooting of “Outrageous” in any way.

Spears and her company Britney Touring Inc. claim to have paid $1.3 million in premiums to the insurance companies that should have guaranteed tour safety coverage.  The companies have 30 days to respond to the suit.
