A Britain's Got Talent camera operator accidentally exposed a magician's card trick during the grand final.
Across the past week, acts have battled it out in five live semi-finals - with five acts put through after receiving the most audience votes and the other five voted through by the judges.
One person who performed in tonight's final was 14-year-old magician Cillian O'Connor. As part of his act, Cillian performed a card trick where he attempted to guess Simon Cowell's card.

Cillian instructed the judge to pick out a card and show the audience what he had picked. Cillian said he would turn away from the judging panel so as not to see the card.
Simon then lifted the card and the cameras zoomed in. The image of the card, a three of diamonds, was broadcast on two screens to show the crowd - however, these screens were located on the stage, directly where Cillian had turned to look.
Picking up on the error, one Twitter user @j11_lee said: "Cillian looks away but sees it on the big screen." @PascalMando6 said: "Did he not just see the card on the massive screen in front of him."
Rhianne tweeted: "He just saw it on the screen." User Phil Not Bob said: "It was up on the big screen he was looking at."
And Buster Sara-Keanen added: "Don't show me the card, he looks away and it's on the big screen #BGTFinal."
