Loos, who allegedly had an affair with England captain David Beckham when she worked as his PA in Madrid, has reportedly been paid £20,000 a week to star in the show, which has seen her jet off to Thailand to participate in exotic health regime with three other celebrities.
Other contestants set to star alongside Loos on 'Extreme Health Farms' include glamour model Jo Guest, Jack Osbourne and DJ's Brandon Block and Normski.
Loos recently came third out of 12 contestants on Five's reality TV show 'The Farm', where celebrities have to work as farmhands for three weeks, while the public gradually vote them off one by one.
Loos was involved in more scandals down on the farm when she had to spend more than 10 minutes pleasuring a pig in order to inseminate the farm's sows.
Five 60-minute episodes of 'Extreme Health Farms' will air in a primetime slot from next year.
The series is being made by Chris Evans' production company Ginger Television behind Channel 4 shows, 'Don't Forget Your Toothbrush' and 'Boys and Girls'.
