The Masked Singer winner Nicola Roberts 'set to RETURN as a judge for the final after wowing viewers with her vocals as Queen Bee'

The Masked Singer winner Nicola Roberts is reportedly set for a spectacular return to the show for the grand final.

The Girls Aloud star, 35, wowed viewers with her vocals as the mysterious Queen Bee last year, and is now reportedly set to be a guest judge in the final on 13th February.

This year's Masked Singer has once again seen social media rife with theories as to who the stars could be behind the characters, with comedian Lenny Henry revealed as Blob last Saturday.

A source told The Daily Star: 'Producers thought it would be really fun to have Nicola back on the show. She was thrilled to be asked and jumped at the chance to return. 

'Nicola knows what it's like to perform inside one of the costumes and try to keep the panel guessing.

'And she knows better than anyone what the contestants are thinking. Producers were hoping that would mean she could approach the game from a different angle and come up with some good guesses.'

MailOnline has contacted representatives for Nicola Roberts and The Masked Singer for comment.

Nicola is one of several guest judges set to appear on The Masked Singer panel, alongside Mo Gilligan, Davina McCall, Rita Ora and Jonathan Ross 

Currently five characters remain in the nationwide guessing game; Sausage, Harlequin, Robin, Dragon and Badger, with theories rife as to which stars could be hidden inside the illustrious costumes.

Nicola was crowned the winner of the first ever UK series of The Masked Singer when she wowed viewers last year as Queen Bee.

Despite her eye-catching costume, Nicola later revealed she'd originally asked bosses for the chance to play a different character.

She told The Sun: 'I wanted to be an angel or a mermaid and they said no, but I managed to tweak the costume and fashioned her up a bit. 

'Under the lights it was so hot and it was warm outside too, because we filmed it back in September last year.

'The amount of layers I had on to conceal every part of my skin and hair was unbelievable.'

The Masked Singer continues on Saturday at 7pm on ITV.
