The Masked Singer season 3 is proving a huge hit and Firework hung on over the weekend.

The last series of The Masked Singer was watched by over 10 million people, and once again Davina McCall, Rita Ora, Jonathan Ross, and Mo Gilligan are wildly guessing who is underneath the costumes.

Firework has exploded onto the screen. Complete with fiery pom poms and a sparkling dress, Firework has certainly made an impact. Ex Coronation Street star Michelle Keegan is among the rumours...

Here's who could be underneath the mask...

Firework performed Domino by Jessie J in the first week.

In the second week, Firework sang Fame by Irene Cara.

Who is Firework in ‘The Masked Singer’ UK? Verbal clues...

 We’ve been given a very simple clue that doesn’t give much away for this costume: “Bang! Here comes Firework.” 

As we wildly guess who it could be with just that simple statement, one idea came to our minds— The Big Bang Theory. Could the iconic Sheldon Cooper (Jim Parsons) be the mystery star? Or could Penny (Kaley Cuoco) be the hidden celebrity? Either way, we have a lot of cast to choose from where The Big Bang Theory is concerned.

Verbal clues aside, could Firework be a scientist? Such as Professor Brian Cox or Bill Nye? 

Or could they be an eager science whiz? Irish comedian Dara Ó Briain is an avid science lover. He even has his own show Dara Ó Briain's Science Club and has written many science books, such as Secret Science: The Amazing World Beyond Your Eyes, Beyond the Sky: You and the Universe and Is There Anybody Out There?

Once we yell “take it off!” at our screens, could one of these famous faces be underneath the mask?

Firework radiated confidence as she excitedly said, “Hiya babs! It’s me, Firework! Oh my God, what am I like? I’ve always been a pocket rocket. A total bundle of energy. But that’s just my style.” Davina McCall suggested that they could be a fashion icon. 

“Maybe that’s because fireworks are designed to make people smile. They’re modeled to be colorful and create joy and happiness!” Mo Gilligan noticed that she had a Northern accent, but Jonathan Ross reckoned she was faking it. “A firework makes any event a party! And you can’t have a party without a few fireworks!” We then caught a glimpse of a porcelain dog and a mirrored lightning bolt sitting on a shelf, along with an artist mannequin shaped into a dancing pose and some china cats. 

“Normally, you find us in the sky, but this one has also lit things up in another fashion. So stand back and shield your eyes, because I’m about to walk into this competition with a bang!” 

She certainly lit up the stage with her performance and the last clue was finally announced: “I light up the street with a different kind of flash.”

Week 2 show clues...

Firework managed to make it through to the next round, which was movie night! But, as usual we were given more clues as to who this masked celebrity could be. “My first performance went off with a bang!” she said, “And I’m ready to shine once more.”

“The reality of being a firework is that you’re always looking for a spark.” Firework was holding a note with the words: “You light up my life- I love you xxx.” Jonathan Ross got the assumption that she could be talking about reality shows and Davina McCall suggested Love Island.

“I mean, just like me, I like things that spark my interest,” she revealed as she walked past some ice skates on the floor. “But I have a very short attention span. I’ve always been that way,” there was a shot of another art mannequin in a dance pose with a moustache on.

“When I was just a little sparkler, I was always jumping from sport to sport. I did all of them. I was a swimmer, a runner, I tried gymnastics…I even won a gold medal once. And I did end up taking part in some games later on in life.” Davina mentioned that they could have won a reality TV show.

Firework then said, “Those early years definitely lit a fuse under me that made me the firework I am today.”

For the next clue section, Firework told us two lies and a truth, therefore only one of the clues would be true. The first one was: "I don't like waste but I have been guilty of dumping." The second: "You couldn't make up how I beat nine hundred people," and the third, "I made a real impression with something I wore."

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

Rita Ora guessed Sporty Spice, Mel C, and Jonathan reckoned it could be Jodie Kidd. Mo suggested that it could be Melanie Sykes or Michelle Keegan, meanwhile Davina said Love Island star Molly-Mae as her guess.

There was a wide range of guesses from the audience at home, with some even suggesting Kerry Katona as Firework.

Week 2 theories...

Jonathan Ross was the first up for guessing and he went with singer Anne-Marie, while Rita Ora also went down the singer route and suggested Dannii Minogue or Sinnitta. Davina guessed TV personality Kate Lawler and Mo Gilligan stuck to his guns from last week and said Michelle Keegan.

Fans at home wracked their brains once again trying to guess and some came up with marathon champion Paula Radcliffe and others agreed that it was Michelle Keegan. Meanwhile, some stuck to their guesses last week of Kerry Katona.
