The former Strictly Come Dancing star was joined by guest Karen Anvil, whose picture of Prince Harry, Meghan Markle, Prince William and Kate Middleton at Christmas went viral, for the segment which saw her take on the role of an angry celeb.
Debbie McGee could be seen approaching the BBC studios in London, trying to keep a low profile, when Karen started shouting her name.
“Debbie, can I get a shot for The One Show?” the amateur photographer asked.
Karen certainly wasn’t prepared for what was to come next, as the 59-year-old launched into a foul-mouthed rant.
“You want a shot of this do you?” snapped Debbie as she squared up to Karen. “A bit of Debbie McGee.
“I’m really fed up of people like you.”
Paul Daniels’ widow could then be seen grabbing Karen’s shirt as she continued to scream at the guest.
“I’m going to take you down, I’ll take you down to f**king China Town,” Debbie shouted.
“I’ll knee cap you. I’ll use you as the f**king garden hose, an actual garden hose.”
Debbie was then seen throwing pieces of papers into the air as she stormed off.
Back in The One Show studio, Debbie and Karen was pictured laughing at the sketch.
Matt Baker, who was presenting the show alongside Angelica Bell, was quick to ensure viewers knew the segment was a joke.
Later on the show, Debbie opened up on her pilgrimage to Santiago, which is set to air on the BBC soon.
Speaking about the difficulties of the walk, she confessed her feet were ruined by the pilgrimage.
“My feet were completely covered in blisters on blisters on blisters,” she explained.
She later confessed the trip was difficult because she was still grieving for her late husband Paul.
The One Show airs weekdays on BBC One at 7pm.
