Britain’s Got Talent guest judge Stacey Solomon was reportedly left horrified after a stunt left one act ‘dripping with blood’ last week.

The TV personality, 36, stepped in at the last minute to replace Simon Cowell, 66, after he suffered a nasty fall ahead of auditions in Birmingham, before filming moved to Blackpool and yet another show hopeful was left injured.

Taking to the stage was an American daredevil who walked naked through a tunnel of electric hedge trimmers as Stacey ‘screamed and hid her eyes’.

Despite completing the stunt, one blade badly cut his arm with footage of the grizzly accident leaking online.

A member of the audience said: ‘He laughed it off like it wasn’t an issue but was hiding his arm behind his back. When he let it drop you could see blood covering his arm and then he accidentally smeared it on his belly.

‘Stacey seemed really shocked, especially when fellow judge KSI talked about giving it a go and she begged him not to.’

Later in Blackpool knife throwing act Alfredo Silva injured his wife Coral while rehearsing backstage, forcing an ambulance to be called.

The source told the The Sun: ‘[Coral] was treated by medics and decided to continue with their audition, but the crew were nervous something might go wrong again in front of the judges and the audience’.

The Daily Mail have contacted ITV for comment.

Last week Simon revealed his absence from the Britain’s Got Talent auditions was because he fell down a flight of stairs.

The TV judge was unable to attend the first two days of filming in Birmingham before reappearing on day three and sporting a bruise on his forehead but no explanation was given.

But Simon revealed the cause of his absence during the auditions in Blackpool when a choir made up of ambulance workers took to the stage.

According to The Sun, Amanda said the ambulance workers might be there in case anything went wrong with Simon again.

He replied: ‘I fell down some steps… and I bumped my head but I’m fine now.

‘I wish you had been around a couple of weeks ago when I actually bashed my head. Seriously – no one sang for me then!’

A source added: ‘Simon bumped his head when he stumbled on some steps. It’s the sort of thing that can happen to anyone. And, thankfully, he’s absolutely fine now.’

The Daily Mail has contacted representatives of Simon Cowell for comment.

Simon previously suffered a terrifying fall in 2017 that forced him to pull out of The X Factor live shows.

The star explained he had fainted due to ‘low blood pressure’, and vowed to start ‘taking good care of himself’ from now on, for the sake of his son Eric, who was three at the time.

Simon admitted the horrific fall had reminded him he was not ‘invincible’, and that he has a ‘responsibility’ to take control of his health as a father.

The media mogul also broke his back in 2020 after a near-fatal e-bike crash. He was thrown off the bike when he was testing the vehicle at his home in Malibu, California.

He underwent extensive surgery after the shock accident including having a metal rod put in his back to stabilise it and he has overhauled his lifestyle in the years since.
