Britain’s Got Talent viewers are convinced they spotted a suspicious problem with TK Magic’s trick. Fans were delighted as the semi final of the live show returned to screens tonight.

The episode aired in an unfamiliar slot on a Sunday evening due to the FA Cup final yesterday. Eight more acts took to the stage in a bid to become the UK’s next star to perform at the Royal Variety.

Simon Cowell, Amanda Holden, Alesha Dixon and Bruno Tonioli were back in the judges’ chairs to review the performances. TK Magic performed one of the most standout routines.

The magicians promised to do one of his most daring routines yet. He started the routine by asking Amanda by picking a number between 1 and 6.

TK had a list of six faces he thought Amanda would have in her contacts. As she selected six, this meant she had to try and Facetime Davina McCall.

Davina soon picked up the call as TK, which amazed the judges. Viewers were similarly impressed, but some were confused as to why Simon told The Masked Singer judge the show “wasn’t live.”

One user said: “did Simon just tell davina ‘it’s not live.” Amy said: “Why did simon say “its not live” to davina?” Lauren took to the comments and suggested this was a joke to catch her out. She added: “Maybe to make her swear lol.”

TK went on to ask Davina to select between a blue and red deck of cards. Amanda, who is a renowned Everton fan, was delighted the blue deck was picked as she said: “Blue for Everton.”

The trick left the viewers gobsmacked as TK knew the card Davina would pick and revealed this with an elaborate mosaic in the crowd which showed the presenter holding her selected card.

However, viewers were suspicious the stunt may have been staged as they picked up on Davina’s glamorous appearance. Dina commented: “Davina was definitely waiting for that call!”

Jade said: “Davina sat with a full face of make up and hair done as well as being dressed up and chilling in a chair almost waiting for that call on a Sunday night is a bit suspicious.”

@Legen_dary93 posted: “Davina looks good with her hair and makeup done just casually sitting in her closet with good lighting for an impromptu call.”

Nichollsliese posted: “What an amazing coincidence Davina was all dressed, with her hair and make up done for a surprise call on a Sunday night!!!!”

TK Magic didn’t progress to the final as he finished in third place on Sunday night’s semi. Hear Our Voice choir were the act who progressed to the final.
