Fans of the Masked Singer fans are convinced that they know who Robobunny is.
The character is among those still competing on the latest series of the ITV show, which is now well into its third season.
Joel Dommett hosts as judges try to guess who the disguised celebrity singers are.
Famous faces who have been unmasked so far include Michael Owen, Jaime Winston and Will Young.
Many viewers are often left puzzled over who it is behind the mask, having been given cryptic clues during each episode.
But fans are now certain they've worked out Robobunny's true identity.
Clues given as Robobunny made their first appearance said: "You thought I was a real tough guy, 'eh? That's just my shell. I'm actually a real softie who's part of a machine."
And following their performance, they explained: "I might be made of metal but that doesn't stop me making a splash."
The most recent hint saw Robobunny say: "You guys have been asking how you get built like me. I never leave the hutch without carrot capsules, great for the eyesight, and grease - that's great for oiling those squeaky joints."
There were also references to the term "diva" and a "cup of Joe".
Judges' guesses so far have included Drake, Vinnie Jones and Top Gear presenter Paddy McGuinness.
Fans, however, remain convinced it is Mark Feehily of Westlife fame, after some initially thought they recognised his voice.
The clues have only given them further "proof".
Taking to Twitter, Helena Cahill said: "Robobunny is Mark Feehily, Westlife broke up, he sang with Mariah Carey hence the 'diva'".
LGDCFC said: "Mark Feehily is Robobunny, Westlife were formed after performing Grease together.
"Strange knowledge, but true"
A Westlife fan account said: "Mark is the diva of the band. He loves Mariah... and calls his daughter a DIVA too! #robobunny"
The Masked Singer airs at 7pm on Saturdays on ITV and the ITV Hub.
