Over the weekend, Calum got offended about comments Coleen apparently made about him in a chat with the other housemates.
Chatting to Big Brother about the bust up yesterday (Monday), Coleen was in tears.
"I love Calum, I just feel a bit bad that's all," she sobbed.
Calum and Coleen's clash at the weekend started with Jamie, Coleen, James J, Stacy, Austin, James C and Brandon are in the garden.
Jamie asked if he is “too nice.” Coleen told him not to be anything “other than you are,” “Although I mess about with Calum, if I was younger and in here it would be you,” Coleen added.
Calum then joined the Housemates in the garden and heard the end of the conversation and as Coleen described him as a 'one night stand kinda guy'. He wasn’t to pleased at being spoken about and returned to the house in anger.
Stacy followed Calum into the house and explained that only nice things were being said about him. He assured her he was “cool” and said that he didn’t need to talk about it. In the garden, Coleen mentioned that Calum was more “sensitive” than he makes out.
Jamie later went to the bedroom and explained the garden conversation was just “banter.”
Calum then went to the Diary Room to talk Big Brother about what he overheard. He said that he had only “praised” Coleen since being in the house.
He explained that it may have been to make Jamie feel better, “But I’m not going to be put down to make someone feel better.”
He added: “I’ve worked my ass off to change a reputation that I was stuck with, I’m not that dude, for someone to f**king call me out like that it f**king pissed me off.”
Celebrity Big Brother 2017 continues tonight at 9PM on Channel 5.
