I think 'Pauline' has entered the house about half an hour ago..
-------------------------
18:38: Pauline reads out instructions from Big Brother: she is not allowed to speak about Australian Big Brother and she will sleep in her own private quarters.
18:27: Housemates are shown a video postcard from Laura, supposedly in Australia and then new housemate Pauline enters.
18:20: Big Brother has called all the housemates to the sofas.
