Kaye Adams was left raging after she was involved in huge production prank during what she believed was a live transmission.
The panelist, 57, exclaimed "what the f***" after a number of blunders plunged the show into chaos.
However it was actually co-star Nadia Sawalha's idea, who ITV bosses forced to run on straight afterwards and admit it was all down to her to ensure that Kaye wouldn't get too upset.
Kaye revealed on the panel: "They all pulled this ultimate prank on me earlier. Take a look at this - this is me genuinely thinking that I am doing a live promo to This Morning while all chaos is going on."
The programme then aired the clip of Kaye reading off the auto cue as panelists Nadia, Linda Robson and Brenda Edwards watched backstage.
However the auto cue suddenly went black while instead of her face being seen on screen, it was an old picture of Christine and Nadia making a funny face behind her.
Like a pro, Kaye tried to carry on despite the dodgy camera angles and odd script.
Kaye quipped: "We've got a few gremlins in! I do apologise. And as Stacey said yesterday-"
However just as she was about to continue, the screen went black again as a fart noise sounded.
The trio of panelists looked horrified behind the scenes as Kaye continued: "She didn't say that!"
As she tried to continue, Kaye remarked: "Probably not all that but lots of great stuff at 12.30!"
The audience clapped and Kaye grimaced at the camera but once it died down, she said to the crew: "And the official television reaction to that is 'what the f***?'
"I have no idea what went out on television but it wasn't good!"
Soon after, Nadia walked on and announced "You just got pranked!"
Kaye looked horrified, exclaiming: "You devil!"
