On Sunday night, the housemates may get suspicious when there's no mention of the latest round of nominations, but it's not because there's another mole.
Instead Big Brother will ask the housemates to nominate one another... face to face and live on Monday evening!
The three or more housemates who receive the most nominations from the group will be the third to face the public vote.
One will be saved in next Wednesday's show while the one housemate with the most votes to evict will be kicked out during next Friday's latest eviction.
It seems that Big Brother is going to be tough this year!
Who do you think will be put up for eviction? Which of the housemates are already getting on your nerves? Share your opinions in the comments below!
Big Brother 2013 airs nightly on Channel 5.
