Big Brother - 'Fake Pauline' Leaves Big Brother

'Fake' Big Brother housemate Pauline has left the house after her fellow contestants worked out she was actually an actress.

Pauline's real name is Thaila Zucchi and although she was pretending to be from Australia, she was actually from Swindon.

During a task to win next week's luxury shopping budget, the housemates rightly guessed that the 'most fake' contestant among them was Pauline.

When asked to line-up on podiums from the most fake to the least fake, Brian spoke out and said Pauline should be "at the end".

Brian was told the truth about Pauline's secret in the diary room earlier this week and he had to tread carefully so that the other housemates did not discover he knew.

"Nothing against you Pauline," he added quickly before saying it made sense to pick her because they knew her the least.

Pauline, or Theila, was then called to the diary room where Big Brother made an announcement that the actress was not Australian and was in fact from the UK.

"Well done housemates," Theila said on a large plasma screen in front of the housemates. "You worked out that I was the fakest housemate in the house. It was so nice to meet you all and I've had an amazing time."

Fake week continues on Friday with a mocked-up eviction that will see whoever is voted out put straight back in.
