Britain's Got Talent fans were distracted by a detail as Amanda Holden took part in a terrifying act that made her think she had "killed" Bruno Tonioli.

Miki Dark performed in Wednesday's third live semi final and, as ever, the gruesome act required some volunteers. Simon Cowell looked very pleased when Miki chose Amanda rather than him and took her up to the stage.

Miki then came back for Bruno and placed him in a guillotine. Amanda, 52, was tasked with holding a rope to stop the blade from falling onto Bruno's neck.

But because this is BGT, the rope fell anyway and Amanda was left stunned. Of course, Bruno was fine and this was all part of the magic, but Amanda admitted she thought she had killed her fellow judge.

Many fans were distracted by a small detail while the action took place, though, and took to Twitter to share their thoughts. It came after she teetered onto the stage in huge high heels.

Cath said: "How is Amanda a part of the act in those shoes tho?" [sic]
