Gareth GatesGareth GatesGareth Gates has got the dancing bug...

And it's making him sick.

Because, reports the Daily Mirror, he and fellow Dancing On Ice contestant, Greg Rusedski, have been struck down with an undisclosed infection.

The paper says both stars are unable to train.

A source told them: "Gareth and Greg both became poorly yesterday and we're all crossing our fingers they recover for Sunday.

"Sometimes it lasts 24 hours, sometimes three days, and leaves you feeling very weak.

"It's important we stop anyone else going down with it. We're doing everything possible to keep contestants apart so they can't cross-infect."

All sounds very serious, what can this mysterious illness be?

Well, we hope Gaz and Greg have a speedy recovery.
