All of the 12 remaining 'Big Brother' housemates are up for eviction this week as punishment for Vanessa discussing her nominations with a fellow housemate.
Derek and Sam received the most nominations from the other contestants, with six votes each, but the show's producers decided to put all of the housemates up for eviction after Vanessa broke the rule of silence regarding the nomination process.
Vanessa was forced to admit to the others that she had told Lesley who she was going to nominate, after the decision was announced.
Sam is currently favourite to be voted out of the show by the public, with odds of 5-4, followed by Roberto on odds of 4-1.
A spokesperson for Ladbrokes said: "Sam ought to start packing her suitcase and make-up bag now, she is red hot favourite for the chop."
