just a theory!
maybe the reason why past housemates and not the winners entered to do the task is because big brother 11 will be an all stars with the winners in the same house?
the reason craig went in is because nasty nick pulled out
and
no one but brian could of gone in for bb8 because the rest were crap!
if they wanted to boost the ratings, why didnt they bring back nadia and pete?
