Britney Spears‘ ex-husband and former backup dancer, Kevin Federline was rushed to hospital on Monday after complaining of chest pains.

The super-sized 33 year old is in Australia filming a weight loss show which will air on Channel 9 Sydney. Federline has already made a televised attempt at weight loss when he appeared on Celebrity Fit Club Boot Camp.

Local reports suggest that Federline suffered a minor cardiac arrest and has been admitted to Sydney’s Mt Druitt hospital for further tests.

He was given oxygen on the scene by paramedics before being taken to hospital. A spokesperson for the Channel 9 show said; “Kevin was at Doonside with the Giants, completing an AFL-related challenge.”

“He did his challenge, which was running and catching the ball, then while his (in-series weight-loss partner) was taking the same challenge, he reported chest pains and a racing heart. Obviously on this show we have a lot of paramedics on standby and they treated him for the first signs of a minor cardiac arrest, called an ambulance and had him taken to hospital.”

Britney has been notified and plans are being made to see if she’s needed to fly to Australia or not.
