Masked Singer UK viewers finally think they have solved the identity of the celebrity performing as Otter on the ITV series.
After two weeks of performances, fans are convinced a TV presenter and Great British Bake Off star is behind the mask.
It was panellist Jonathan Ross who initially made the prediction, and now fans think he might be on to something.
Clues for Otter include references to working in radio, someone having filmed serious roles while also possible references to medical and police themed TV series.
There was also a clue to Bake Off, and possible references to comedy and to The Rocky Horror Show.
Taking to Twitter after Jonathan's prediction, fans linked all of the above clues to TV presenter Mel Giedroyc.
According to IMDB, Mel has had roles in TV including Holby City - while she also featured in a police spoof.
Mel narrated The Rocky Horror Show Live, and hosted Bake Off before its move to Channel 4 - while she also works in radio.
Taking to Twitter, one fan said: "Mel Giedroyc sounds about right."
Another tweeted: "It wouldn’t surprise me if Mel Giedroyc is Otter… it’s the mannerisms and the positioning of the hands on the waist…. It’s how Mel would."
A third fan tweeted: "Otter has to be Mel Giedroyc!!!"
It comes as another character appeared to be rumbled, after a celebrity may have let slip they were on the show.
There has been a number of clues for the character Knitting on the ITV show, such as a magpie, the number 26 and references to crafting - prompting various guesses from viewers.
Some are convinced that it's Claire Richards, behind the mask, with the Steps member fitting many of the clues and having even fuelled the theory over the weekend too.
The singer took to social media a few days ago to share an update about their plans for the weekend, revealing to their followers that they were engaging in a bit of crafting.
Clues that fit the singer include a magpie that may potentially be a reference to Step's song One for Sorrow as well as a riddle that fans have linked to their song 5,6,7,8.
A more recent clue, in which the character said they wanted to 'leave the light on', further fuelled the theory - with fans suspecting it's a reference to song Scared of the Dark.
And despite fans being convinced it's her, Claire wrote in a tweet that it could be Jane McDonald, 59. Fans suggested she was trying to "put [them] off the scent" though.
The Masked Singer UK continues next Saturday at 7pm on ITV1 and ITVX.
