For this week's shopping task, Housemates will be reliving significant moments from the past eleven years of Big Brother! The Task will take place over three days, culminating in a live performance of Pie Jesu by Michelle in front of Friday night's eviction crowd. Here's a sneaky peek at the first part of housemates' Retrospective Task: Makosi On Big Brother 6, as 'Big Brother's unluckiest Housemate', Makosi's secret mission was to gain the most nominations. Again, Big Brother names Makosi as the unluckiest Housemate – this time however, everyone else is in on the joke. Makosi will be called to the Diary Room and told that for the next hour she must try and become the most unpopular housemate. However, in a sneaky twist, Makosi's fellow housemates will all watch this Diary Room conversation on their plasma screen, and will be told by Big Brother that the real secret mission is to ignore anything Makosi does in her attempt to make herself unpopular, and should instead tell her how popular she is! Later this afternoon, Makosi will be presented with a gift wrapped box, inside which is her coveted mobile phone. Unluckily for Makosi, it has no battery. Other unlucky things will happen to Makosi throughout the course of the task - so stay tuned! Makosi will also be told she will be cut out the show – we give her a green body suit covered in ping pong balls to wear explaining that it is technology to delete her from the show. Preston On Celebrity Big Brother 4, Preston took part in an experiment task in which he tested whether liquor chocolates could get you drunk. This time, Big Brother is seeing whether he can eat the same 48 liquor chocolates without being sick. Makosi's unlucky day will also continue tomorrow. Nick, Nadia, Chantelle, Brian, Nikki and Michelle will take part in their challenges over the next two days.
