Eagle-eyed The Masked Singer fans spotted a massive clue tonight that may prove Hedgehog's identity.
Viewers have been trying to work out who the prickly customer is for weeks - but many are now convinced it's obvious after seeing a hidden clue.
During his opening video tape, Hedgehog was seen dusting a framed photo of Billy Connolly.
"I've always looked up to people as heroes," said Hedgehog, which made the judges shout out the comedian's name.
Many viewers claimed this indicated it was Jason Manford behind the mask, until they spotted a red ball to the side.
In a blink and you'll miss it moment a red cricket ball flashed up on screen with the name "Michael' written on the side.
This led many viewers and Donny Osmond to guess that Hedgehog is the famous opera singer.
However, others have suggested it's too obvious a clue - with Rita Ora guessing it's Michael's pal Alfie Boe because of his theatre experience.
Many The Masked Singer viewers are now convinced that the hedgehog is Michael Ball.
One fan asked: "Is that not a “Michael” on a “Ball” in hedgehogs VT?!"
"Are we just going to ignore the fact that the ball has ‘Michael’ written on it...Hedgehog has to be Michael Ball," added another.
However, others suggested that the 'Michael" on a ball clue could actually be a decoy.
"That means it’s Alfie Bo," claimed one viewer.
Another agreed: "They’re putting bluffs and false clues in though"
Davina McCall guessed that Hedgehog was comedian Jason Manford as he also sings in West End musicals.
While Jonathan Ross admitted he had actually changed his mind and now thinks the prickly fellow is comedian Rufus Hound.
After his performance, the Hedgehog said: "I thought the panel's comments were very interesting actually and it was lovely to see Donny again…oops."
Does he actually know Donny Osmond? Or is it another lie?
*The Masked Singer airs Saturdays on ITV at 7pm
