With White Dee from Channel 4 documentary series Benefits Street also due to appear on The Big Benefits Row Live's panel, pre-show hype focused on the potential for a clash between the two vilified media personalities.
But it was former Apprentice contestant Katie that attracted the most ire from fellow panellists and the studio audience, as host Matthew Wright attempted to stress on more than one occasion that there was no need for personal insults.
Katie first lost her cool after needling comments made by former face of Max Factor Annabel Giles that were hardly even picked up by microphones in the studio.
"I'll point where I like," Katie flapped after Annabel objected to some expansive gestures.
Annabel later scolded Katie, 38, that "adults are talking", drawing the response: "All I hear is somebody that wanted to be a model, but didn't make it."
Looking a little flushed, reality TV character Katie told the former I'm a Celebrity contestant to "get a grip" during a later segment."You'd be really dangerous if you knew what you were talking about," shot back 54-year-old Annabel.
Another guest, Reverend Steve Chalke, expressed frustration that the sideshow was pulling focus from the issues supposed to be under discussion, blasting the rows as "cheap television".
He fumed: "I think the problem already is that we're here and we say we want the grown up, mature debate about a benefits system and about dependency culture and making sure that benefits doesn't lead to dependency.
"We need a serious debate about those things, but we don't have it by name calling. And we don't have it by making cheap television programmes."
The show also featured clashes between former Tory cabinet minister Edwina Currie and both anti-poverty campaigner Jack Monroe and a contributor to Channel 5 documentary On Benefits and Proud.
