The Masked Singer UK viewers are pretty sure they have worked out the celebrity donning the Firework costume on the ITV series.
From Atomic Kitten stars, to West End performers and TV favourites, a number of names have been thrown into the rumour mill.
But some fans think the vocals and the latest batch of clues might have led to them solving the case for once and for all.
They're now tipping it to be former Coronation Street and Emmerdale actress Hayley Tamaddon under the mask.
The former Dancing On Ice champion and stage star is a guess by several viewers, after clues about ice skates and outfits.
Hayley performed to the Girls Aloud song Jump on ITV's Soapstar Superstar in 2007, which might be linked to the clue about jumping.
She also performed on the celebrity edition of Stars In Their Eyes many moons ago, and the vocals do sound a little like those of Firework.
Hayley has also performed in Thoroughly Modern Millie and Chicago, with a recent clue linked to the latter it seems.
Taking to Twitter, one fan wrote: "I’m catching up on #maskedsingeruk i think firework is Hayley Tamaddon."
Another said: "It’s Hayley Tamaddon. I’m sure of it," as a third added: "Firework is hayley tamaddon."
The comments kept coming too, with another viewer adding: " Fire work is Hayley Tamaddon."
A further tweet read: "Firework sounds like Hayley Tamaddon to me."
Other viewers shared particular clues, pointing to children and to Dancing On Ice, believing it was her.
I t's a double elimination on the ITV guessing show this weekend, as two characters will finally be unmasked.
Amid fans believing they have worked out all of the characters, and their true identities, Joel will announce a double exit for the first time this series on Saturday.
The news was confirmed on Twitter and at the end of last weekend's episode, that saw Poodle unmasked as Keane singer Tom Chaplin.
After several names including Mika, Gary Barlow, John Barrowman and others, it was finally revealed that it was none of the above.
Instead, Tom took off the Poodle mask, leaving panellists Mo Gilligan, Davina McCall, Rita Ora and Jonathan Ross in shock.
Five characters have been found out so far, including Poodle, Lionfish, Snow Leopard, Bagpipes and Chandelier.
The Masked Singer UK airs Saturdays at 7pm on ITV.
