Simon Cowell cheekily asked Britain's Got Talent hosts Ant and Dec to change up their presenting techniques, saying they were "spoiling" the show.
The Geordie pair present Britain's Got Talent : The Champions each week, welcoming back past contestants and those from other series around the world.
But judge Simon admitted in the latest episode that something the boys did each episode "spoiled" things for him, and he asked them to stop.
As the hosts asked him how he was finding the shows, he said: "Genuinely I do not have a clue who's on each night so I love it."
Simon then added: "So try not to give it away in the breaks because you keep saying who's coming up and that spoils it."
Ant and Dec laughed off the moment, before Ant said: "That's kind of our job."
Dec then told him they would warn him going forward, but they carried on as usual.
He said: "Every time we're going to do it we'll nod at you and you put your fingers in your ears."
As the show went on, Simon could be seen in the background sticking his fingers in his ears every time an act was about to be revealed.
Viewers picked up on the hilarious scenes, taking to Twitter to see if anyone else noticed.
One fan commented: "Love that @SimonCowell just stood there with his fingers in his ears!!"
Another asked: "Why is Simon sticking his fingers in his ears.."
There were five former BGT acts on the show on Saturday, while the remaining four were on other versions of the show.
Britain's Got Talent: The Champions airs Saturday evenings on ITV.
