Just when the housemates think they know all there is to know, Big Brother turns everything on its head for the next week.

And the best part is that everyone will know EXCEPT the housemates.

Big Brother’s “Fake Week” kicked off on Friday’s eviction show. The housemates were introduced, via the Living Area’s plasma screen, to their new ‘Housemate’, Pauline. Having been ‘evicted’ from Australia’s Big Brother she will join them in the UK, on Sunday. They were also told that their fellow housemate, who had just been evicted, was jetting to Australia.

What the housemates didn’t know was that Pauline is in fact actress Thaila Zucchi and that she chatted with Davina on their doorstep! Pauline won’t have to fly 24 hours to get to the house or suffer jet-lag. But they won’t know that.

Big Brother’s faking it will begin with Pauline’s entrance, following an interview with Dermot on T4’s Sunday outing of Big Brother’s Little Brother (12.45pm C4). The housemates will then be set a number of Australian themed tasks to make their new ‘housemate’ feel at home. What they won’t know is that the real task is actually guessing if Pauline is a fake, or not.

Her current housemates think she’ll be sleeping in a specially decorated bedroom next door to theirs. Actress Thaila will also be visiting Big Brother’s Little Brother for latest updates throughout her stay and Big Brother will also be setting Pauline secret tasks each day to keep the housemates thinking…is she…isn’t she?

In what will be the weirdest week of their lives, the housemates will also face a week of Big Brother’s fake tasks and twists, ending in a ‘fake eviction’ that viewers will be in on.

Throughout “Fake Week” viewers will know exactly what Big Brother is planning for the Housemates. But will the Housemates work it out?
