With the twist rumours going round of the final in some way effecting the normal BB, and with a CBB housemate going in to BB theory ruled out with practicability factors, I have my own theory.
Each housemate after leaving will choose two housemates to enter the big brother house the following night. This could be from pictures, numbers etc. This would make 14 housemates (16 if Jedward choose separately).
Probably from a shortlist of about 30, ensuring there's a good mix. Maybe each housemate will quickly be shown VT of four housemates and asked to choose two to go in?
Discuss.
