the moment bb finishes they start to plan next years show,so how did they know so far in advance that a couple were going to apply,re,wedding task,also isnt it a bit of a coinidence that mario an lisa have been on other shows and the first time they audition they get accepted.if no couples wouldnt of applied would they have cancelled the wedding task.?

The housemates are chosen months before bb actually starts- this gives them time to plan everything.

[Barbie]

i think some tasks are based on the housemates chosen

[jonsep]

there chosen only weeks befor it starts due to not given away identies

The task on launch night was probably chosen because of the fact that two of the housemates were a couple. The twists/tasks on launch night are probably decided no more than 1/2 weeks before launch night.
