Prize surprise tonight
One housemate will win £50,000 tonight. In a shock live show, 'Big Brother' contestants will be put to a series of tough questions to determine the winner of the prize.
The unlucky bunch will also be forced to nominate in front of each other live on air.
The grand prize of £100,000 is not affected by tonight's contest.
The live show will broadcast on Channel 4 at 11.05pm.
Meanwhile, Darnell has vowed to give all his money away if he wins the show.
The songwriter - who threatened to walk out yesterday because he is fed up of being "angry" all the time - said material wealth means nothing to him.
He said: "If I win, all I'm going to do now is give it away to charity, give it to my mum or blow it on my friends.
"It's not going to make me happy at all. It sucks and that's why I get so mad."
