Two daredevil gymnast brothers from Vietnam, known as The Giang Brothers, have won a shot in the 2018 final of Britain’s biggest TV talent show with a stunning performance on Friday.

In a cliff-hanging live semi-final night, the gymnasts and circus performers from Ho Chi Minh City left the crowd and judges jaw-dropping with a death defying performance.

Despite holding a hinted impression about their act, the judges of the talent competition still have been wowed when the pair, Giang Quoc Co, 34, and Giang Quoc Nghiep, 28, officially took the stage at the semi-final.

The two artists have combined the acrobatic moves with balancing their bodies to show the beauty of tough muscular on stage.

The climax of the performance is when Quoc Co, blindfolded, balanced Quoc Nghiep atop using only head-to-head contact and moved backward - toward and upward – downward a set of stairs.

Judges Alesha Dixon and Amanda Holden were startled as the dual had a little staggering in the last backward footstep on the stairs.

"I am very impressed with you, and I cannot believe it,” Alesha Dixon commented on the performance.

Amanda Holden praised the two artists, describing it was as if they had just seen the performance by the winners of the Britain's Got Talent 2018.

The brothers from Vietnam eventually defeated a magician runner-up by two votes from judges Simon Cowell and Alisha Dixon and voting public in the UK to become the show’s finalists.

The older brother Quoc Co told the media later on Saturday that he could not believe they could make it this far.

"We are already very satisfied with this achievement no matter how the result of the finale is," Co said in a voice that failed to hide his delight.

The final of Britain's Got Talent, featuring ten winners from the semi-finals plus one wildcard act that will be decided by the judges, will be broadcast live on June 3 on the British channel ITV.
