WATCH: Britain's Got Talent Stunt Takes Shocking Life-Threatening Turn
There's no denying that Britain's Got Talent has seen its fair share of dangerous tricks, but Saturday's episode is set to see one of the most daring acts to date, and all doesn't go quite to plan.
Vietnamese act, the Giang Brothers, left audience members gobsmacked after undertaking a series of death-defying stunts on the variety show.
The brothers - aged 29 and 33 - explained how they had been performing some hair-raising acrobatics together since they were children, and practice up to six hours a day in order to perfect their skills.
However, despite hours of practice, the pair's routine quickly left audience members on edge, as one brother began to balance on the other's head.
Things then took an even more breathtaking turn, as one of the brothers took a slight tumble - a move which sent the entire stadium into panic mode.
Luckily, the act quickly recovered, and nobody was injured.
Clearly shaken by what she had witnessed, Amanda Holden said: "It was utterly incredible and my heart was in my mouth for all of it.
"I don't know where you find the strength from."
The same episode also sees 13-year-old Manchester terror attack victim Hollie Booth take to the stage with dance troupe, Rise, leaving the judges sobbing...
Teenager Hollie sadly lost her aunt, Kelly Brewster, in the Manchester Arena bombings, and also had her own legs shattered in the attack.
The performance left Simon Cowell speechless and choked up with emotion.
The BGT judge said: "You know what, Hollie, it is, wow, this is difficult.
"I'm trying to put... to go through what you went through, and turn a negative into a positive is unbelievable.
"Because what these people did, because they're cowards and the fact you can come on stage, do what you did, and make such a positive statement with your friends, I'm very proud of you. In fact, I salute you."
