Earlier today, it was revealed that Katie and three of her fellow housemates face the boot in the next live show, and Calum and Michelle are concerned their pal will be shown the door.
Speaking in the garden in a new clip, posted on the official CBB website, Calum told Michelle: "I don't want Hopkins to go."
Michelle replied: "I know, I fear for that. I fear for that."
The pair were chatting in the garden about their time in the house and it's fair to say both appeared downtrodden following Perez Hilton's explosive return.
After Calum told Michelle he's enjoyed his experience with her, she replied: "Me too, babe. I've enjoyed making a new friend. It's been an interesting ride. It's not done yet. I just want to be in the final with my friends. I just want to enjoy what's left."
Referring to Perez, who is up for eternal eviction following a public vote, the US star added: "I just want to know what happens at that last bit. Are they going to keep him in here with us?"
Calum replied, "Or...?" before Michelle concluded: "Or...it's may the best man win."
Last night, viewers saw the aftermath of Perez's return to the house following his two-day stint in a secret room. And boy, was there fireworks.
Not only did Calum come to blows with Nadia Sawalha following comments Perez had made, Keith Chegwin has also lost his rag with Katie Hopkins.
Meanwhile, Perez was shown goading Katie H in the kitchen while attempting to lick her face.
Earlier today, it was reported that CBB bosses axed a scene which showed Perez making an 'explicit demand' to Katie. CBB have declined to comment.
