In tonight's show, Big Brother gathers the Housemates on the sofa where they are informed that Alicia and Calum had a conversation about nominations.
As a result, Housemates are not allowed to use the hairdryers or straighteners, until further notice.
However it seems that the pair can't stop talking about it.
In the house today (Tuesday), Calum snapped with Alicia for saying he was two faced, singling him out and making him feel guilty that she was facing eviction.
Alicia insisted she was "only joking" but Calum walked off as Alicia reacted: "We can't even be in the same room now."
Later, the model went over to talk to Calum as the pair tried to sort out their problems.
"I was only joking, please don't take it offensively. I know it wasn't just you [who nominated me]," Alica replied.
"It makes me feel out of ease," Calum replied, "I didn't give you f**king grief when you nominated me."
Alicia told the model: "Every time I feel like when I come over to talk you, you walk off. I feel you've got to know everyone [else] really well whereas with me I feel you don't like me."
"Maybe with more time we'll get to know each other better..." he said, before concluding: "Let's just drop it."
Celebrity Big Brother airs tonight at 9PM on Channel 5.
