Anyone who saw the Big Brother launch show tonight (and I can’t imagine anyone missing it!), will know about the first four housemates’ secret task.

Mario and Lisa entered the house as a couple, but after they were joined by Stephanie and Luke, Big Brother gave them their first task. Mario and Lisa must pretend that they are not a couple, but instead 43 year old Mario must convince the other housemates that he is with 19 year old Stephanie. If they pull it off, the four taking part in the task will escape next weeks public vote. If they fail they will all be up for eviction.

At the end of the launch show, Davina McCall announced that Mario and his new girl Stephanie will be getting married this Sunday, and they’ll think it’s for real!!!! How brilliant!
