CELEBRITY Big Brother housemates are due to find out who is first up for eviction tonight during a surprise live show.

Contestant Terry Christian has already secretly nominated Ulrika Jonsson and Lucy Pinder thanks to his position as Head of the House, with one other celebrity also to be selected.

Celebrity Big Brother bosses have promised the former Word presenter’s mission will be unveiled during a show tonight during which the celebrities are “enlightened” live on air about his secret picks.

Big Brother also has an extra twist up its sleeve with the housemates being forced to make a “difficult” decision. This reportedly will involve them voting to save one of Christian’s nominations.
