Who was Lionfish in The Masked Singer UK? It turned out to be Will Young!

The competition sadly didn't go swimmingly well for Lionfish on The Masked Singer UK season 3 as he was just the third celeb to leave the show. Poor Will! He was really good and surely should have been on the show longer. Will of course won the first-ever series of Pop Idol back in 2002 (Gareth Gates was the runner-up).

The 42-year-old tweeted: "Who’s that behind the mask? It’s me!! I am #Lionfish    #MaskedSingerUK". Below we've kept in the guesses we had and others before Will Young was unmasked. One of them was even right!

Lionfish impressed the judges and audience with their singing of Nessun Dorma by Giacomo Puccini the first week. Second-week Lionfish lost in a sing-off with Stop This Flame by Celeste.

Who is Lionfish in ‘The Masked Singer’ UK? Verbal clues…

As well as an outrageous costume, the only clue we have to go off for Lionfish is: “Hear them roar, it’s Lionfish.”

Of course Lionfish don’t roar, but they are venomous. Jeremy Wade has often encountered some of the world’s most dangerous fish on his hit series River Monsters, where he has come face-to-face with some of the most peculiar aquatic creatures across the globe. The biologist has also starred in other popular shows such as, Mysteries Of The Deep, Jeremy Wade’s Dark Waters and Unknown Waters with Jeremy Wade. Could his expert wrangling skills be helpful in catching the hearts of the public as well as the fish in the deep water?

If we’re going with the fishing concept, famous comedians and lifelong friends Bob Mortimer and Paul Whitehouse decided to go on a fishing adventure in their series Mortimer and Whitehouse: Gone Fishing. They’re both entertainers, so it would be unsurprising to see one of them take to the stage and perform as Lionfish!

Who is Lionfish in ‘The Masked Singer’ UK? Costume clues…

As usual, the costume doesn’t give anything away, but one guess was made as to who could be swimming about as Lionfish was TV presenter and adventurer Simon Reeve.

Simon has made documentaries from all over the world, including, Mediterranean with Simon Reeve, Indian Ocean with Simon Reeve and Caribbean with Simon Reeve. In one particular episode of Caribbean with Simon Reeve, Simon dived the reefs searching for invading Lionfish in Barbados.  

Simon Reeve believes the Lake Disttrict is one of Britain's most romantic regions, but also looks at the effects of climate change there.

Who is Lionfish in ‘The Masked Singer’ UK? Show clues…

Lionfish began their clue package with: “One, two. One, two. Hello, my beautiful creatures, and welcome to The Fishbowl!” followed by German and French subtitles. 

“I’m Lionfish, and it’s my pleasure to be your host this evening.” Davina McCall started questioning whether Lionfish was a man or a woman. “I’m aiming to bring some “sole” to the proceedings. I hope that joke wasn’t too cheesy.” Mo Gilligan suggested a soul singer, before the clues went on. 

“They say it’s never too late to start, and trust me, I should know. I might be a lionfish, but I’m very gentle, I promise. I only use my barbs to defend myself when absolutely necessary.” Jonathan Ross said that “barbs” can be an attacking joke, and Lionfish proceeded with: “So, fear not, I’m here to have a good time. And I’m hoping to get under the skins of this fabulous costume.” Davina McCall began to think that they could possible be a drag act. There also featured an Easter egg on a table during the video. Could that be a massive clue?!

Lionfish amazed the judges with their singing skills, until the final clue was revealed: “I’ve appeared in places I’ve never been.”

Who is Lionfish in ‘The Masked Singer’ UK? Theories… 

Davina went for musical star Lin-Manuel Miranda, meanwhile Mo went for soul singer Heather Small. Rita Ora also thought that Lionfish could in fact be a woman and suspected it could be Ellen DeGeneres and finally, Jonathan guessed John Dee.

Lionfish left viewers at home puzzled and there was a diverse range of guesses—some even mentioned Gino D’Acampo and Will Young!
