Dancing on Ice judge Jason Gardiner threatened to boycott Sunday’s Dancing on Ice final unless he received an apology from Karen Barber, say the papers.

The Sun reports that the notoriously catty panellist made the threats after Karen – who has coached the skaters this series after leaving the judging panel – accused him of lying in a magazine interview.

The 49-year-old contradicted Jason’s claim that she had been given a warning over the pair’s onscreen argument last month, when the pair fell out over Johnson Beharry VC’s skating.

“Jason saying I was given a warning was totally untrue,” Karen said. “I did nothing wrong, so that wasn’t the case at all.

“But I wouldn’t hesitate to do it again if Jason crossed the line. Standing up for myself is all part of the new, confident me!”

However a friend of Jason’s told the paper, Jason saying I was given a warning was totally untrue. I did nothing wrong, so that wasn’t the case at all.

The feud erupted last month after Jason criticised Johnson’s performance and Karen leapt to his defence. The 45-year-old responded by saying, “If your opinion still mattered you’d be on this panel.”

Karen then jabbed her finger in his face and told him, “You are so offensive. You bring so little to this panel.”

However a source close to Jason told The Sun that he would still appear on the show in spite of the pair’s falling out.

“Jason was furious and has had enough of the rows with Karen and wants an apology.But he is a professional and will be on the show on Sunday.”

The final will see Sam Attwater, Laura Hamilton and Chloe Madeley compete for the series title.
