Britain's Got Talent is set to take a dramatic turn on Saturday night as a contestant is set to invite Simon Cowell up on stage to be part of his nail-biting act.
In tense scenes, the sledgehammer-wielding entertainer Kranthi will ask the 65-year-old judge to be his volunteer to help him out during the audition.
Simon is told to lie down and keep very still, while the audience watch on in shock and Ant McPartlin shouts: 'What are you doing? You must be mad!'
The crew come onto the stage and warn Simon of how important it is he stays still as 'things could go wrong'.
The act then puts on a blindfold, which earns a gasp from the crowd, before her blindly smashes the watermelons which are placed just inches from Simon's head, with the giant sledgehammer.
Alesha and Amanda are out of their seats and keen for Kranthi to stop his act, as the weapon lands just centimetres away from Simon's face.

Discussing how he never used to get up on stage, but now can't seem to get off it, Simon explained: 'So it started when a couple of times I agreed to get involved in something. And it's almost like…how can I put this?
'The producers on this show just love my pain! So I thought, “Well, if you like it that much, I'll just go along with it!” But often it’s not fun what they do to me.
'I mean, the stuff they did to me this year, wow! There was one point, and I'm not lying, I genuinely thought, “That’s it. It's over”.'
Recalling the terrifying moment, he quipped: 'A guy nearly smashed my head in with a sledgehammer. I genuinely thought my days were numbered.
'He was slipping all over the place and sweating so much. That’s what freaked me out because when I got up close, I thought, “My god, his adrenaline's on such a high.”
'Then it doesn't matter what he's done in rehearsals, he's falling around, he's sweating like that, things could go wrong. And I thought, “I shouldn't be doing this”. Amanda and Alesha were not happy.'
He admitted: 'When I looked at them, saw their faces and really were worried. I mean, look, I don't want to push my luck, I did say at one point that I think I'm running out of lives here.
'I've had everything thrown at me this series. It's scary but good scary. It's like going on a rollercoaster, you know it’s going to be really frightening and you shouldn't do it, but you kind of want to!'
Meanwhile, Amanda admitted: 'I just thought it was insane and I can’t believe he did it.

'And the only thing that Simon was told when he went up on stage was to keep still, which he did not do, obviously.
'He never does what he’s told. So it scared me but he’s an adrenaline junkie. I think he does it because Eric likes seeing his dad do those kinds of things. He likes seeing him take risks.'
Viewers will have to wait for Saturday night's instalment to see how Simon's dangerous stunt goes.
The ITV talent show sees judges Simon, 63, Amanda Holden, 53, Alesha Dixon, 46, and Bruno Tonioli, 69, give their verdicts on acts from around the country.
A new series began just last month and has already showcased a range of performances from a naked comedian to impressive opera singing.
But, the much-loved ITV hit received a surge of Ofcom complaints from viewers last week, many about a particularly gruesome act.
American performer Auzzy Blood took to the stage in last weekend's instalment and shocked the judges and audience with his daring routine.
During his stunt, Auzzy put a corkscrew and meat hook through his head and nose, and out of his mouth.
The scene was so dangerous that a warning was put out so viewers do not try the stunt at home - with Dec reiterating the point during the segment.

The horrifying act was dressed head to toe in gothic attire and had painted their face in skeleton-like paint.
After twisting the corkscrew and hooks, he then inserted a tube into their nose and out their mouth, instructing Simon to drink from it.
For the final part of the terrifying act, he pulled himself up into the air from a rope with a hook hanging from their mouth and nose.
However, ITV received 57 complaints after the show which brought the total number to 828 so far.
An Ofcom representative said: 'The vast majority of complaints were about Auzzy Blood's routine. These are additional complaints to those reported last week, and the cumulative total 828.'
