Britain's Got Talent viewers have been left impressed yet baffled over 2022 act Matricks Illusion, as they performed this weekend.
Even the judges couldn't quite work out how the quick change act was done, with the group managing to change clothes at speed - but that wasn't all.
The group members on stage also kept changing constantly within seconds, with a clever phone trick also appearing to show those on stage moving behind the screen.
One hilarious moment saw one member of the group transforming into judge Simon Cowell, and hosts Ant and Dec confessed they had to double take.
Brother and sister illusionists Alex and Emily first formed the group in the early 2000s, and they lead the group now along with several members performing all sorts of trickery.
But BGT 2022 isn't their only stint on ITV, and viewers may recognise them from their previous TV appearances.
In 2014 or 2015, the illusionists appeared and performed on Bradley Walsh's ITV series, Keep It In The Family.
Their website reveals they've also worked alongside Stephen Mulhern, Diversity, KSI and Roman Kemp, while they appeared on the YouTube hit The Sidemen Show prior to their latest venture.
The group have also performed at a number of venues and events, so viewers may be familiar with their work.
Once again, the group left everyone in disbelief and amazed at what they pulled off, with them sent through to the next round.
Their talent will no doubt land them a spot in the live semi-finals, but this has yet to be confirmed.
Viewers raced to Twitter over the weekend, sharing their love for the act as they tried to work out how the group did it.
One fan said: "The quick change act was good, as another said: "So brilliant I have no words."
A third added: "These were my favourites last night. Absolutely brilliant! Well done!"
Britain's Got Talent returns on Saturday at 8pm on ITV.
