Britney Spears’ ex-husband, Kevin Federline, was rushed to a hospital in Australia on Monday after suffering chest pains while taping a celebrity weight loss reality show called Excess Baggage.

Federline, 33, was given oxygen by the show’s onsite paramedic team and then transferred by ambulance to Mt. Druitt Hospital in Sydney, where he underwent further tests.

A spokesperson for Channel 9 -- which produces the 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.
