The Masked Singer fans believe they know who could be underneath the Jacket Potato costume amid rampant speculation.
With the last instalment of the ITV show just a week away, Jellyfish, Phoenix, Rhino, Jacket Potato and Fawn take to the stage in the semi-final with host Joel Dommett once again hosting.
Once again judging panellists Rita Ora, Jonathan Ross, Davina McCall and Mo Gilligan try to guess their identities, accompanied by guest panellist Peter Crouch.
The semi-final is a double elimination, so two contenders will be unmasked at the end of the show, leaving three to compete in the final.
As the fourth series winds to an end and each of the 12 mystery celebrities are finally unmasked from under their elaborate costumes, Masked Singer fans are now pointing to a celebrity chef for the identity of Jacket Potato.
Using the clues that have already been revealed on the programme, as the guesses from the panel, the ITV viewers at home might have got it right as they guessed it could be TV chef James Martin.
Taking to Twitter, one fan wrote: “Utterly convinced James Martin is Jacket Potato.”
A second added: “Ok, I'm going to say it.. James Martin for Jacket Potato as he has Spud U Like and loves butter.”
“Fully convinced James Martin is jacket potato am locking it in,” a third echoed as another viewer pointed out: “James Martin can play guitar - Jacket Potato.”
However, other fans have claimed that Jacket Potato could be Bon Jovi’s Richie Sambora confirmed, with one tweeting: “Jacket Potato is one million percent Richie Sambora. ‘Go Your Own Way’ – he left Bon Jovi 10 years ago. And I know that voice and that playing anywhere.”
It comes after Jacket Potato appeared on stage with a guitar to perform Fleetwood Mac’s “Go Your Own Way”.
Jacket Potato’s shiny appearance consists of a silver jacket and pants, a shirt that looks like baked beans, polystyrene container shoes, and yellow gloves.
The contestant’s mask is a giant potato with a split in the middle with butter inside, underneath which they also wear sunglasses.
The first clue as to Jacket Potato’s identity was: “Their vocals are sure to get you creamed – it’s jacket potato!”
He declared: “I’m no angel, but I’m one sweet potato! Tonight I’m gonna deliver a smash hit!”
Previous guesses from the judging panel have included Davina guessing Ade Edmondson and Mo going for Matt Lucas, while Rita went with Jack Black and Jonathon went for Ozzy Osbourne.
