Kevin Federline Hospitalized Following Weight-Loss Reality Show Challenge

Kevin Federline, the ex-husband of Britney Spears, has been hospitalized after suffering what is believed to have been a “minor” heart attack while filming a weight loss reality show in Sydney, Australia.

According to multiple reports, Federline, 33, was rushed to a Sydney hospital after complaining of chest pains during a challenge on Australia’s Excess Baggage TV show.

The former backup-dancer underwent a series of blood tests and is expected to remain at the Sydney hospital overnight.

A spokesperson for Australia’s Channel Nine told Contact Music:

“Kevin was… completing an Afl-related challenge. He did his challenge, which was running and catching the ball, then while his (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… They want to do blood tests and Kevin is likely to be there until at least late tonight.”

DigitalSpy reports that this is the second time K-Fed has suffered a medical problem on the Excess Baggage set since filming began nine weeks ago. In December Federline was struck down with heat exhaustion while completing a similar challenge.

Kevin has been in a well documented battle with his weight since his breakup with Britney in 2007. Prior to Excess Baggage, he appeared on the VH1 reality soap Celebrity Fit Club back in 2010.

In other recent news, Kevin Federline welcomed a daughter with his girlfriend, ex-volleyball player Victoria Prince, in August 2011.
