Mo Gilligan, Davina McCall and Joel Dommett have also shared that they were shocked to find someone they knew inside the masks.
This year the line-up includes such crazy concepts as Air Fryer, Bubble Tea, Eiffel Tower, Dippy Egg and Bigfoot.
And one reveal annoyed the team so much, Davina, 56, has said she stomped off stage.
She said: “The funny thing was that all of us have met this one character. We were kicking ourselves.
“They did very, very, very well in fooling us all. We all should have got them, all of us. No excuses, really.

“I just couldn’t help myself storming off when I saw who the person was.
“There have been many people on the show who I have met in passing, but this was a real friend, someone I have known for years.
“It’s embarrassing. It was, I think, the greatest surprise I’ve ever had.”
Mo, 35, said: “I think early on sometimes you know someone and you’re just like, ‘I know that clue. I know who that person is. I’ve connected the dots’.
“You get an aura from them. There’s one I think is my mate.
“The viewers will have to wait and see whether that ends up happening . . . ”
Meanwhile on his own secret connection, Joel, 38, added: “To be in the industry for that long, to go from being the warm-up guy to then hosting a show and having someone from my past standing next to me — it just feels amazing to have had that journey.
“That’s why I feel like you’ve got to be nice to everyone at every moment, because you never know when that person is going to be giving you work in the future or stood next to you in an insane costume.”
- The new series of The Masked Singer begins on Saturday at 7pm on ITV1.
