SIMON Cowell shocked America's Got Talent audiences tonight by joining in with a dangerous knife-throwing stunt after a terrifying mishap.
The talent show legend put himself at risk leaving both viewers and his fellow judges open-mouthed.
On tonight's episode of America's Got Talent, brothers Tyrone and Michael Laner presented their act, Blade 2 Blade, which they described as "very, very dangerous".
The audience and judges Simon, 62, Howie Mandel, 66, Sofia Vergara, 49, and Heidi Klum, also 49, were all stunned as the two tossed knives within inches of each other at a frantic pace.
As if the stunt wasn't dangerous enough, the brothers then added a model in between the duel.
She spun around on a pole holding two small rubber shields as they threw blades within inches of her.

At one point, Heidi believed the stunt had gone wrong as a knife failed to land safely in the shield and deflected in the direction of the model.
Heidi was worried for her safety, exclaiming: "I think he hit her a little bit!"
But with all three performers on stage appearing to be unharmed, the act finished to rapturous applause and Tyrone and Michael awaited the judges' feedback.
Given the danger of the act, fans were shocked when Simon then decided to take up the brothers' offer to join them and stand in the middle of the knife-throwing for an encore.

Simon looked scared for his life as his fellow judges watched on in horror.
Howie tried to reassure Simon: "I guess it's safer than being on a bike," referring to the TV personality's 2020 cycling accident which saw him break his back in three places.
On Twitter, viewers shared their shock, with one writing: "Simon wanted danger, he got it."
Another asked: "Simon what are you doing?"
"I cannot believe Simon did that!" shared a third.
LIVING ON THE EDGE
Simon looked terrified as the knives flew at high speed around his head.
Members of the audience and all his fellow judges watched on nervously holding their hands to their open mouths.
But he survived the act unscathed and hugged it out with the performers on stage.
Stepping down to the judges' desk, he looked happy to be alive.
"They're real!" he said, impressed by Blade 2 Blade's bravery and accuracy.
Simon told Howie that he could feel the blades going by him, and he admitted to Sofia that his heart was "going crazy".
But the slightly shaken fame-maker was grateful for the experience, telling Tyrone and Michael: "This means a lot to you, I can see that.
"I'm definitely saying yes. Thank you very much."
DOPPELGANGER
Simon has enjoyed getting involved with the acts of season 17, and last week, was shocked when he met a contestant with exactly the same face.
An act called MetaPhysic Media demonstrated the use of artificial intelligence (AI) to create what they described as "hyperreal content".
The futuristic act comprised of opera singer Daniel Emmet on stage, and two other men behind the scenes.
As Daniel belted out Chicago's You're The Inspiration, a screen on stage showed an AI portrayal of Simon singing the song himself.
For the impressed judge, imitation proved to be the sincerest form of flattery.
