Britain's Got Talent fans declared that they "couldn't look away" as a "gruesome" act left Simon Cowell speechless on Saturday night (April 26).

During tonight's live semi-final, professional sword swallower Auzzy Blood took to the stage, following his viral audition that left viewers squirming in their seats.

Once again, Auzzy left the crowd and judges in shock as he hooked various items through his nose. The judges were seen looking visibly aghast, while Simon stood up from his seat to look away in horror.

"It's really turned my stomach... But at the same time, it's something that I just couldn't take my eyes off. It's ghoulishly, horrifically brilliant," said Amanda Holden.

"I didn't think you could go any further than you did in your audition, but oh my gosh you did and I just dread to think whatever dark things you've got planned for us. Horrific."

Simon added: "Disgusting, nauseating, repulsive and I love you... You have amazing stage presence. I love acts that kind of make me scared but also want to watch it again."

BGT viewers quickly took to X (formerly Twitter) to share their reaction to the act, with one writing: "Ofcom's gonna be busy tonight."

Another added: "OMG it's Auzzy blood. This act is disgusting and not for family viewing."

Meanwhile, other viewers were impressed with Auzzy's performance, with one person declaring: "Unpopular opinion maybe but Auzzy Blood is by far the best act tonight."

Another added: "Auzzy was disgusting to watch. And I loved it," while a third said: "It's like a horror show, but you can't look away, it's fascinating."

Sadly, Auzzy's act didn't win over the public and he was immediately sent home. Scottish singer Vinnie McKee received the highest number of audience votes, earning him a place in the final.

Elsewhere on tonight's semi-final, dance troupe The Blackouts received the coveted golden buzzer from Amanda Holden, also securing their spot in the grand final.
