The fake Aussie babe made the housemate's day when they discovered that an Australian Big Brother contestant would be coming to the UK house.

Pauline, was in fact an actress, Thalia Zucchi, employed by Big Brother to try and fool the housemates into thinking she was real. As a part of fake week Pauline also had to complete secret missions set by Big Brother, such as pretending she was psychic.

But she was rumbled. Carole predicted the exact truth about Pauline. Brian was let in on the secret and without letting anyone know he knew he successfully managed to get Pauline to stand on the most fake housemate podium.
