Kevin Federline has been rushed to hospital after suffering a suspected cardiac arrest.
The 33-year-old ex-husband of singer Britney Spears was filming for Australian TV show 'Excess Baggage' when he complained of chest pains and a racing pulse and was taken to the Mt Druitt Hospital in West Sydney on Monday.
A spokesperson for TV network Nine, said: "Kevin was at Doonside with the Greater Western Sydney Giants, completing an AFL-related challenge.
"He did this 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."
Kevin underwent an ECG test and it was found he had not suffered a heart attack, but he is being monitored.
It is not the first time Kevin has had to have medical assistance - he collapsed due to heat stress in the first episode of the show.
