LATEST: Sexy star Britney Spears fears her recent knee injury will force the cancellation of her eagerly-awaited world tour, causing a devastating loss of money.

The TOXIC singer collapsed on the set of her OUTRAGEOUS music video in New York on Tuesday night (08JUN04) and was taken to hospital twice to undergo arthroscopic surgery to remove cartilage in her left knee.

But the injury is so serious her management are worried she will have to drop her ONYX HOTEL TOUR altogether.

A close source says, "Britney's in a lot of pain and she just can't risk continuing with the tour if there's any chance it could affect her in the long-term. There's so much money riding on this, no-one wants to speak too soon."

The 22-year-old is due to appear in Connecticut on 22 June but may be forced to pull out if keyhole surgery is required.
