A new housemate entered the Big Brother House on Sunday. The other housemates know her as Pauline who has been transferred from the Australian house, but Big Brother fans know her as Thalia Zucchi, an actress from Wiltshire in England. Thalia's arrival launches Fake Week and she will be acting on BB's behalf to create as much tension in the house as possible. Thalia must stay in character whilst in the house except for when she is in the diary room where she can be herself. The task for the housemates is to rumble Thalia in order to win the luxury shopping budget for this week. Already we are beginning to see housemates have their doubts with Charley Uchea having said "She ain't even been in Australia. She's probably been living in London and picked up an Australian accent."Not only do we have a fake housemate this week, BB is also holding a fake eviction! Housemates will nominate as normal and it appears as if the housemate is leaving for good. But when eviction time arrives on Friday night the evictee will be interviwed, hear what the fellow housemates have to say about them and will then return to the house.
