Britain's Got Talent mind readers DNA shocked the judges tonight - but one part of their trick may have been revealed.
DNA are made up of 43-year-old Andrew from London and 29-yer-old Darren from Essex.
They are a double act of mind readers and were hoping for yeses from the BGT judges this evening.
They performed a number of tricks in front of the audience and panel, apparently reading the minds of Amanda Holden and Simon Cowell.
And just before the audition concluded, they revealed one last twist to it all, having pulled off another trick right under the eyes of the panel and audience by changing their T-shirts with apparently no one noticing.
After the audition, many were quick to rewind and find out how they did it, with eagle eyed viewers pinpointing the pair seemingly switching their T-shirts while hidden behind Simon Cowell as they escorted him to the stage, at around 1:40 in the above video.
Of course, that was only one part of the act and how they did the actual mind reading is anyone's guess...
"We're all really spooked out," remarked David Walliams after the audition tonight.
"You did actually read minds and I don't know how you do that... it's creepy but good," Simon Cowell added.
With four yeses, the duo sailed through to the next round.
Other acts in tonight's show included 8-year-old comic Ned Woodman, dancing PC Dan Graham, singing impressionist Jess Robinson and the The Missing People Choir, who get the emotions going with original song “I Miss You”.
Britain’s Got Talent 2017 continues Saturday nights on ITV.
Straight after this evening's show at 9:25PM you can tune in to Britain’s Got More Talent on ITV2 with Stephen Mulhern.
