Here's a picture preview of tonight's dramatic Celebrity Big Brother 2015 highlights, ahead of the live twist.
It's a two hour marathon show this evening on Channel 5 from the earlier time of 8PM, hosted by both Emma Willis and Rylan Clark.
In tonight's show we see the housemates nominate for the latest time, ahead of what they think will be an eviction on Tuesday night.
There are rows ahead of the Diary Room votes as Katie Hopkins and Perez Hilton AGAIN clash.
The pair argue as Perez describes his Big Brother experience as 'traumatic' and says he feels like the show has "defecated on my soul".
In the evening and Big Brother surprises the group with a special task to win their letters from home.
The eight remaining housemates are split into pairs and go head to head, with only one pair being able to receive their letters.
It means at least four housemates will miss out and it leads to tears from some of the group.
Of course, tonight's show will climax in a big twist which will see Emma enter the house herself for a surprise, instant eviction.
Catch all the action from 8PM tonight on Channel 5.
