Kevin Federline, Britney Spears' ex-husband, suffers minor heart attack
The Daily Mail reports that Federline, 33, was participating in an Australian rules football challenge for the show when the heart problems hit.
"He did his challenge, which was running and catching the ball, then...he reported chest pains and a racing heart," says a spokesperson for Australia's Channel Nine. The spokesperson adds, "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."
Federline has struggled with his weight in recent years. In 2010 the former dancer was a participant on the TV series " Celebrity Fit Club."
Federline is being held for observation. It is uncertain whether he will return to the show.
