The Big Brother housemates will be forced to nominate each other face to face live on Channel 4 tonight (Wednesday).

The contestants are worried there will be a surprise eviction after they were not asked to nominate as normal on Monday.

But the Channel 4 website stated: “Housemates have been complaining about people being two-faced, back-biting and putting on an act in the House. They should be careful what they wish for. Big Brother has a big surprise for them…”

It’s been revealed Davina McCall will host a live show asking the housemates to choose two of their rival contestants to face the public vote for eviction on Friday, giving their reasons in front of each other.

The clock will be ticking as the housemates – who usually nominate in secret in the Diary Room – choose the two people they want to face the boot.

In a second twist, the chosen two evictees will then go head-to-head in a game of jeopardy for the chance to win a jackpot of £50,000. The series winner’s prize of £100,000 will not be affected.

Mohamed, who was chosen to be Head of House by his fellow contestants this week, is immune from nomination and is guaranteed a place in next Friday’s final.

Davina will introduce the Big Brother highlights show on Channel 4 at 9pm before returning for the later show as the housemates are forced to make their open nominations.
