Britain's Got Talent viewers believed they had worked out one illusionist's trickery on the ITV talent show on Sunday night.
Miki Dark took to the stage to perform for the crowd and judges Simon Cowell, Alesha Dixon, Amanda Holden and newcomer Bruno Tonioli.
As the auditions continued ahead of the live semi-finals later this month, one act certainly had viewers and the judges talking.
'Scary' illusionist Miki Dark is said to be known for 'swallowing razorblades, blindfolded knife throwing and engulfing his own head in flames' according to his official website.
On Sunday night be brought terror to the room, as he performed a creepy act for the judges and in front of hosts Ant McPartlin and De Donnelly.
But it didn't take long for viewers to predict there was more to the routine, which consisted of a trick with fire.
Miki has actually met Simon and Alesha before on America's Got Talent, with him performing on the show in 2020. Alesha was a guest judge on the US series, while Simon judges on both shows full-time.
Three years on and Miki was back, this time on the BGT stage and this time he left everyone screaming, as he appeared to set Simon on fire.
Simon was tasked with sitting on a chair with a cover placed over his head, which the illusionist then poured lighter fluid over.
The judge's head was then placed in a box, before Miki set the box on fire - leading to Amanda and Alesha staring in horror, as audience members screamed out.
After, Miki removed the box and revealed Simon was fine, despite appearing to be set on fire.
The judges were visibly shocked but relieved to see Simon was unharmed, after finding the whole thing terrifying.
Viewers watching at home were quick to claim that they knew exactly how the illusionist performed the trick, suggesting a fireproof covering was used or that a secret box wasn't shown to viewers.
Taking to Twitter, one viewer said: "Well obviously there was another box round his head and the fire was between the 2 boxes. Acting he didn't know what was happening. Getting too staged now this."
Another fan tweeted: "a fire proof box sectioned off all round the top and sides, with lighter fluid already doused on beforehand, and water Simon's head completely shielded anyway. This is basic magic that's been done for a century."
A third viewer said: "So a box with a false roof, false front and false sides nearly tricked us into thinking he set Simons head on fire."
Meanwhile a fourth viewer said: "Have the audience and judges never seen a fire-proof hood used in special effects? It was entertaining but not dangerous in the slightest."
Britain's Got Talent continues next Saturday at 8PM on ITV1 and ITVX.
