Both Bianca and Calum try and calm things down, but John is fuming!
He accuses Nicola of “making up all these things about me” and added: “When I come out of this, seriously we’ll see the real story of the whole thing.”
Nic really touched a nerve!
Calum then tells John that everybody just “wants respect for each other” in the house, but John wasn’t having any of it.
He retorted: “I get it, you’re just trying to save the day like a hero!”
Then Calum lashes out and things start to get a little but shouty: “I’m just trying to be a gentlemen!”, said the later George Best’s son.
As the argument heats up, the X Factor contestant said: “Imagine me saying all these things about you… Imagine you in my shoes, being told all these things about yourself!”
It seems the twins are getting the better of Calum, as he later had to take some time out in the smoking area and blasted the brothers.
