BRITAIN'S Got Talent stars Matricks Illusion are at the centre of a fix row after it was discovered they have appeared on ITV before.
Viewers of the talent competition were left furious after finding out that the magicians had performed with TV host Stephen Mulhern.
Matricks Illusion - made up of brother and sister illusionists Alex and Emily - took to the stage with a quick change act over the weekend.
They were sent through to the next round by impressed judges Simon Cowell, Amanda Holden, Alesha Dixon and David Walliams.
However, eagle-eyed viewers could help but notice it was NOT the first time the group had been seen on television.
Many took to social media to note how the BGT act had previously been on ITV, as part of Bradley Walsh's Keep It In The Family.

The group have also taken part in hit YouTube series The Sidemen Show, alongside KSI, Roman Kemp and Diversity.
Presenter Stephen, 45, who hosts Britain's Got More Talent after the live programme's later in the competition, also worked with them.
The illusionists have also performed at a number of events up and down the UK - making it likely some viewers already knew of them.
It comes as furious viewers have taken to Twitter to slam the show as "a fix" after it made its debut over the weekend.

Many were left furious that the golden buzzer was pressed for professional singer Loren Allred, but not for teacher Tom Ball.
One fan wrote on Twitter: "Tom Ball not getting a golden buzzer is more proof that #BGT is completely fixed.
"Producers organising golden buzzers for acts who are already professionals in their field so they can push their shows and records and reap the financial rewards."
Another said: "Apparently that comedian has already got a stand up show on Amazon Prime. Yet another wasted golden buzzer."
Axel Blake blew Simon away on Sunday night with his funny gags - and was given a free pass straight into the final.
Fans pointed out that the comedian already has a stand-up show on streaming service Amazon Prime.
Meanwhile, Singer Loren Allred was given a golden buzzer pass to the final by Amanda.
It was revealed that she was the voice behind The Greatest Showman song Never Enough, which also sparked multiple "fix" claims.
Elsewhere, they felt that a dad who was secretly entered into the competition by his two daughters was likely also "fake".
Some eagle-eyed viewers questioned the sweet moment's authenticity after spotting a microphone on Nick's shirt.

Britain's Got Talent denied the claims, saying they told him he was given a microphone as part of their "gogglebox audience".
"He was totally unsuspecting. We did this so we could mic him up without him suspecting a thing," they said.
