Britney’s ex-husband, Kevin Federline, was hospitalized due to heat stress while filming a weight loss show called Excess Baggage, the Aussie version of Celebrity Fit Club, according to Eonline.com.

A show rep tells E! News that their first shoot was in November in the Kimberley region in Outback Western Australia, which is “widely regarded as one of the most remote and hostile parts of the country,” and during the shoot, under advice from the show’s medic, Kevin was “taken to hospital as he was showing signs of heat stress.”

Kevin was since released and resumed filming. The show airs on the Nine Network next year.
