Fans of The Masked Singer took to Twitter to voice their shock at the House Husbands star being identified as the prawn.
"The Prawn is Darren McMullen. I did not guess that at all #maskedsingerau" wrote one fan, followed by many who were convinced it had been Kris Smith.
Last week, Grant Denyer sparked rumours that he is a contestant on The Masked Singer after revealing that he has been taking weekly singing lessons for several years.
Punters have suggested that the 42-year-old is the celebrity voice behind the Dragon costume.
“I like music. I play guitar and I play the drums. I love the art of singing, it is the most incredible craft and it is so impressive when you watch someone that can do it well,” Grant told The Daily Telegraph.
The clues we know so far about the Dragon include the fact the audience was hearing him “like never before” in his mask.
The judges’ guesses were Daniel Ricciardo, Ben Gillies, Waleed Aly and Mark Skaife.
