The pair had starred alongside each other in Celebrity Big Brother last year where they were involved in several rows in the house.
But today in a “peace talk” on Loose Women, Kim hit out at Coleen and branded her “lying trash” before walking off the set.
Now, a spokesperson for Kim has released a statement detailing how “incredibly upset” she feels following the fall-out.
He claims Kim was mislead over how the proceedings would take place on the ITV show.
“Kim was invited onto Loose Women as she was told Coleen wanted to hold peace talks with her,” the representative told Mirror Online.
“When she arrived this morning, Kim was briefed and told Coleen would speak first and give her reasons for their row. She was told Coleen wanted to bury the hatchet.
“However when Kim walked on set, Coleen refused to speak first and made Kim do all the talking.”
He added: “This incident has left Kim incredibly upset and she feels disappointed with what happened.”
On Loose Women, Kim broke down in tears as she raged at Coleen for making her life “hell” and “bullying her with seven other people” in the Borehamwood bungalow 18 months ago.
Kim believed the studio audience were “laughing” at her and began to hit out at Coleen.
“Look you folks can laugh all you want,” she declared, “I’m going to tell you something now and then I’m going to leave. I had a very very sad childhood, a brutal childhood, it was terrible.
“It was a brutal rotten childhood, it was terrible and I can’t describe what I went through.
“Then when I went in the Big Brother house I was very upset in that house and I pretended I wasn’t, I pretended I was fine.”
Janet Street-Porter attempted to intervene and insisted Coleen wanted to “draw a line” under their feud.
However, Kim continued with her argument as she accused her former housemates of “laughing” at her.
“I will never forget what the likes of her and everybody else were doing, they were laughing at me. I lose my temper but it’s better than that.”
Pointing toward Coleen, Kim declared: “She is trash.”
“She’s not trash,” Janet chimed in as Kim made her way out of her seat to go backstage.
The programme then cut to ad break without Kim reappearing on the show.
Coleen confessed she was rattled by the exchange as she told the panel: “I’m shaking, that was the like The Jeremy Kyle show.”
Loose Women airs weekdays at 12.30pm on ITV.
