The Masked Singer's Knitting might have been exposed just one episode into the new series.
Knitting took to the stage on Sunday evening to belt out a rendition of Becky Hill's hit Remember.
But from the moment they sang their first note, Knitting had viewers suggesting they knew exactly who was behind the mask.
As the mystery celebrity delivered a great performance, fans believed the recognisable vocals belonged to a member of the band Steps.
The clues also pointed to the band and possibly one member in particular, so fans were sure that, considering the clues and the voice, it was none other than Claire Richards under the costume.
Clues included a possible accent, which could have been faked, and hints to someone who had worked on daytime TV.
With the costume and other teasers, it suggested the mystery person liked or was good at crafts - while fans also noted a magpie on the wall in the clue video.
Knitting's final riddle was: "Knitting is easy, it's the crossing of sticks. Count all of your stitches, there should 26."
Panellist Jonathan Ross suggested this could be linked to someone who has run the London Marathon, which is just over 26 miles long.
Steps singer Claire did run the marathon in 2012, while viewers also commented that she was into arts and crafts.
The number 26 could also mark how many years it has been since Steps' debut single 5,6,7,8 was released.
The solo magpie could be a nod to the rhyme One For Sorrow, which also happens to be the name of a Steps song.
As for the morning TV reference, Claire has hosted fashion segments on This Morning and used to be on the Loose Women panel - while she has made numerous daytime TV appearances during her career.
Taking to Twitter, viewers were convinced they had it all worked out with one writing: "Claire Richards is Knitting."
Another agreed: "Knitting is absolutely Claire Richards! She’s crafty, loves knitting, 26 clue refers to Steps being around 26 years, magpie for One For Sorrow! My queen!"
A third fan added: "Watching last nights #MaskedSingerUK again with my mum and I’m now convinced #knitting is @_ClaireRichards."
Meanwhile a fourth viewer tweeted: "Late clue courtesy of @djleekeewhich adds to the Claire from Steps theory for #Knitting - magpie on wall in VT package…One For Sorrow?"
The Masked Singer continues next Saturday at 7pm on ITV1 and ITVX
