Four up for Big Brother eviction
Four Big Brother housemates face eviction from the Channel 4 reality programme during the live show later.
Housemates initially nominated Dave, Govan, Shabby and Ben, but Shabby was given the opportunity to win a task and choose someone else to take her place.
The 24-year-old picked Mario, who is now facing the public vote in the 11th and final series of the programme.
Beyonce lookalike Rachael was the first person to be booted out of the Big Brother house last week.
Cracks have already started to appear amongst the group, who have been punished by Big Brother for talking about nominations.
Some housemates have been asked to complete a variety of secret tasks.
Corin was asked to tell absurd lies to her fellow housemates, while Shabby had to compliment Ben several times, after they had argued.
The winner of the current crop of housemates will be joined by previous winners and notable contestants to determine the ultimate Big Brother champion for a two-week special to mark its departure.
The opening episode of the current series attracted an audience of 5.1 million, slightly down on 2009.
This week's evictee will be announced on the Channel 4 show at 2100 BST.
