Is Doncaster's Sheridan Smith set to be unveiled as winner of TV's Masked Singer?

Viewers have been speculating for weeks that the popular actress and singer is Sausage in the wacky ITV show where a group of mystery celebrities perform songs while keeping their identity under wraps in a series of outlandish costumes.

Just three star names are left in the show – with the final set to air at 7pm on Saturday.

This year’s final will be contested by Robin, Badger and Sausage.

Last week, former Great British Bake Off host Sue Perkins, was unmasked as the Dragon.

Harlequin was revealed to be singer Gabrielle while Sophie Ellis-Bextor, Spice Girl Mel B, Martine McCutcheon and former footballer Glenn Hoddle are some of the other celebs who have been unmasked.

Actor John Thompson, Sir Lenny Henry and A-ha singer Morten Harket were also eliminated during the series.

Many fans have been convinced for weeks that Sheridan is inside the sausage costume from a number of clues dropped during the series.

These include a bag of potato snacks, her huge vocals and a comment about her hair colour being certified by law.

This could be linked to her former TV series Two Pints of Lager and a Packet of Crisps, and her starring in Legally Blonde The Musical.

Earlier in the series, judges Jonathan Ross, Rita Ora, Davina McCall and Mo Gilligan were asked who they thought it was, with three of them naming Sheridan.

However Joss Stone and Stacey Solomon have also been touted as possible contenders for Sausage.
