Ant McPartlin and Declan Donnelly have revealed a hidden secret about their suits for the Britain's Got Talent live shows.
The Geordie presenting duo have scrubbed up very well this week for the semi-finals with an array of different outfits.
However, their suits contain something inside that viewers never get to see on-screen.
The boys filmed a video for Instagram where they revealed all, admitting not many people are aware of their little trick to know which suit is theirs.
Speaking backstage at the Apollo Theatre, Dec said: "So not a lot of people know but we put patches in our suits so we know which suits are which and tonight I feel like one of the acts on the show.
Dec then opened up his jacket to reveal a sticker of a playing card on the inside of his jacket.
He continued: "Because I go like 'pick a card, any card' and and I knew you had that card because it was the ace of spades. It was your card all along."
And then opened up his jacket to reveal which patch was hidden inside his suit jacket.
Showing off a big smiley face, the presenter said: "And we knew that would make you happy."
"It's magic," whispered both the boys as they drifted in front of the camera.
The lads are gearing up for tonight's Britain's Tot Talent live semi final.
They gave a one hour reminder to viewers on Twitter in a short video clip.
Dec said: "We'll be on the telly in an hour."
Then turning to Ant, who was looking shorter than his co-host because they were on a staircase, Dec cheekily said: "You alright down there?"
Ant didn't look too pleased as Dec jokingly gave him a pat on the head.
*Britain's Got Talent airs tonight on ITV at 7.30pm
