Big Brother is set to spring a 'bombshell' twist on the Celebrity Big Brother 2015 housemates tonight.
Last night the group nominated as usual and have been led to believe that one of them will be going in a normal eviction on Tuesday night.
However what they don't is that one of them will be walking out of the doors tonight.
There will be marathon two hour long show - split into one hour segments - starting at 8PM this evening hosted by both Emma Willis and Rylan Clark.
The first 60 minutes is billed as Celebrity Big Brother: Live Bombshell and will see a "big surprise" revealed to the remaining housemates.
At 9PM and Celebrity Big Brother: The Fallout will air as the housemates react to the show's big twist.
Exactly what's going down hasn't been confirmed but Emma previously teased: "We're having a live extravaganza, there will be live hits to the house and then there will be an eviction, and I'm going to go into the house and drag them out with me."
And Emma hinted of the twist: "We are having letters from home, in some capacity."
Yesterday saw the group paired up and take part in a competition to win messages from their friends and family.
Two pairs of celebs faced off against each other but the task meant that only a maximum of half the housemates could get their letters from home, and there was the chance that NO ONE would.
What do you think will be tonight's twist? Who do you want to see evicted? Tell us in the comments below!
Celebrity Big Brother 2015 airs on Channel 5 this evening at 8PM.
