The nation is hooked on zany guessing-game show with The Masked Singer, which sees a series of celebrities don elaborate disguises as we try and guess just who is behind the mask.
Octopus is a colourful and bubbly character whose performance suggests she’s no stranger to the stage. But who is she? Is she really Kylie or Danni Minogue?
With theories flying around on the internet, who really sang on tonight's show?
Well according to Jonathan, it's an Emmerdale star due to the fact that the secret singer was wearing wellington boots in the VT before tonight's performance.
Sharing his thoughts on the identity of the songstress, the judge revealed:
"You were wearing wellies and referenced a farm. You have to be from Emmerdale".
The VT also mentioned 'the jungle', which drove fans wild on Twitter as they speculated the singer is an Emmerdale actress who appeared on I'm A Celeb.
Now fans are thinking that Octopus is in fact Gemma Atkinson.
In 2015, Gemma began playing the role of Carly Hope in the ITV soap opera.
The star Atkinson has also appeared in Peter Pan at the Manchester Opera House in December 2008 when she took the title role alongside John Thomson who played Captain Hook.
With obvious singing ability, could this be the face behind Octopus?
Other Emmerdale stars could include Sheree Murphy who is best known for playing Tricia Dingle in the rural soap.
In November and December 2005, Murphy appeared on the ITV reality show I'm A Celeb, finishing second to Carol Thatcher.
She was noted for being "scared of everything", and for her sweet persona; as well as embarrassing her husband Harry Kewell with comments such as "he's got a peachy bum".
With reference to 'the jungle' and the wellies in tonight's show, could it be Sheree who's hiding behind that mask?
Lucy Kate Pargeter is also another front runner after tonight's shock episode.
The actress is best known for her roles as Helen Raven in Crossroads and Chas Dingle in Emmerdale.
Lucy Kate also finished third in the 13th series of the ITV reality show I'm a Celebrity...Get Me Out of Here! in 2013, and was covered in fish guts in one iconic trial scenario.
Could the fish guts be related to her iconic Octopus outfit?
We'll soon find out.
The main theory previous to this is that Kylie Minogue is under the huge Octopus costume.
The teeny performer without a doubt has a recognisable voice, but she is also a skilled singer who could doctor her own vocals to sound American.
And lets not forget about her iconic link to Jason Donovan when her character Charlene married his in Neighbours.
The judges certainly think it’s Kylie, but are they barking up the wrong tree?
