Within minutes of them all arriving, Big Brother will reveal that they are not yet official housemates and that they will not get access to the full Big Brother house. They will have to individually earn their housemate status over the first three days of the programme in tasks.
Until successful they'll only have access to the empty living room, a toilet and the garden. They won't be able to get at their suitcases and will have to spend their first night sleeping on the living room floor.
If they want to wash, the eight men and eight women will have to fetch cold water from the garden in a hole-ridden bucket. And forget the food budgets of previous years – meals will consist of cold porridge. To escape the spartan set up, contestants must triumph in tasks which will challenge their pride and will require them to go head to head. Only those who prove their mettle will be allowed into the "real" house, which has full facilities from day two. On Sunday viewers will pick who they want to be housemates from those still left in the barren house.
Unsuccessful candidates will be given their marching orders, and there'll be no post show interview with series host Davina McCall to ease the blow.
"They are in for a massive shock. It is going to be nothing like they expected, says the show's spokesperson. "'It's going to make the first few days incredibly uncomfortable and I wouldn't be surprised if some of them can't hack it and ask to leave - which they are free to do."
