Auditions for the current series of BGT continued last Saturday with Amanda Holden, Simon Cowell, Alesha Dixon and David Walliams on the panel.
One of acts appearing on the show were Mind2Mind, made up of couple Marina from Ukraine and James from Milton Keynes.
After Marina identified items from Amanda's handbag while blindfolded, the new Heart FM breakfast host secretly picked Italy from a randomised list of countries. The illusionists helped her transmit that thought to Simon, who was amazed that he ended up writing the same nation down on his board.
"I'm in total awe of your power," said David.
"You've done a great job when everybody's scratching their head wondering how you did it," noted Alesha.
Now Mind2Mind have unveiled the secret behind their seemingly magical mind reading skills.
James told the Metro newspaper: "It’s something called a second sight act, where Marina can kind of see through my eyes and sense things that I sent to her.
"Then later on, the right environment and the right connection, we can actually show other people how they can do it."
Marina insisted there was no collusion between the couple and the judges.
She said: "We can say that, 100%, we guarantee we’ve not met any of the judges prior to the televised competition.
"We would have loved to, but it didn’t happen!"
With four yeses, Mind2Mind are through to the next round - but will they make the live shows?
The line up for the semi-finals will be confirmed at the end of the final auditions this Saturday night on ITV.
Britain's Got Talent 2019 continues this Saturday night at 8PM with the last round of auditions.
The live semi-final shows begin the Monday after, May 27.
