The acrobatic duo, who live in Russia, wowed the audience with the first part of their routine as they showed off their impressive balancing act and athleticism.
But Cowell and fellow judges Amanda Holden, Alesha Dixon and David Walliams were left cowering behind their hands and shifting uncomfortably as they attempted a terrifying balancing act with swords.
Yes, swords. In their mouths. SWORDS.
As the pair attempted to get the weapons aligned in their mouths, things started to look a little hairy. The pair started shaking and looking close to collapse so they aborted the mission.
But, down and not out, the Armenian duo decided to give it one last shot as the audience screamed around them and the judges were left awestruck.
Cowell tapped his chest as he calmed down after the act, not that he’d watched most of it because he turned away through practically all of it.
“I almost was going to say you can't do this,” he told the Vardanyan Brothers. “Because in all my years this is the most dangerous act I have ever seen on any talent show.”
Holden added: “It was exciting, terrible. I can't wait to see what you can do next.”
The duo then told the crowd that they have “more difficult” tricks up their sleeve, if they are to get the chance to perform again.
But will they get through to the next round? You’ll have to watch to find out.
