On last Wednesday's episode, the pair sparred as they attempted to make peace over their longstanding CBB feud, Kim dubbing Coleen "trash" as she walked off, the latter in turn calling Kim "vile".
"It really threw me when she came out and attacked us all and I was just as upset as everyone else," Coleen has now told Metro. "At one point I actually felt myself smiling. I thought, 'Is this actually happening?' I don't wish her any ill but she's such an actress.
"In one sense, I was relieved that people would know that I wasn't exaggerating about her behaviour on Celebrity Big Brother. From the moment she woke up to when she went to bed, she constantly attacked us and then claimed we were all ganging up on her.
"At one point, which they didn't show on TV, we all suggested she had counselling because she is so full of rage. So her behaviour on Loose Women probably didn't surprise me as much as it did the others."
For her part, Kim asserted during her Loose Women appearance that she was "ganged up on" during her time in the house, and denied a suggestion that she "clashed and argued" with several housemates, adding: "No, I didn't argue with every single person."
Coleen continued: "Linda Robson, who is the kindest woman in the world, was trying to be so nice to her and it was bizarre, Kim kept hitting her hand away.
"What upset me were the trolls afterwards who said I had bullied her. It was really unfair for people to troll us and blame us. The whole experience was horrible and I couldn't stop shaking."
After the episode aired, broadcasting regulator Ofcom confirmed it had received thousands of complaints. It plans to assess the complaints against its broadcasting code to decide if they need further investigation.
Kim has also called for Coleen to be fired from the programme.
Coleen revealed that Linda was left "shaking for the rest of the day" after the episode, and that Janet Street-Porter was "horrified" by what happened.
"I had been told that Kim wanted to make amends," the presenter continued. "And even though I said she didn't need to, her management really wanted her to come on.
"I thought she'd come on and it would be a chat, and we'd agree to put it behind us. Instead, she came out with all guns blazing.
"It was like she had a script and was going to stick to it. She claimed she'd had a terrible childhood and that she had been abused but my own sister was abused and she doesn't act like that.
"I hope that if Kim has serious mental health problems she gets help and that the people who love her protect her from live TV."
Digital Spy has reached out to Kim's representatives for comment.
