The rumours come after viewers tweeted their theories that Masked Dancer ‘Onomatopoeia’ could be a US star from the show The Big Bang Theory.

The ITV show sparked theories on twitter, with one viewer tweeting: “#MaskedDancerUK Onomatopoeia someone from Big Bang Theory?”

Backing up the theory, a fellow viewer commented in reply: “I mean Bang is an onomatopoeia and Kunal Nayyar has been here quite alot recently.”

“He was even nominated for a bafta recently.

And the first part of Nayyar is said “neigh” which is another onomatoepia.”

Another fellow viewer tweeted: “Onomatopoeia #MaskedDancerUK I was thinking someone from Big Bang Theory after the clues.”

A fourth chimed in, stating: “Someone who was in big bang theory #MaskedDancerUK”

Based upon the contestants’ costumes and dance routines as well as a handful of hints, the judges and viewers of the show try to deduce who is behind the mask.

The celebrities perform whilst trying to hide their identity.

The character ‘Onomatopoeia’ is all about his brightness and words associated with sounds.

From the clues so far, the main guesses are Simon Bird and David Tennant.

Each week the characters perform a dance routine and viewers vote for their favourites, with the two with the least votes being left in the bottom two, where the judges can choose to save or ditch either contestant.

The show is a spin off of the show The Masked Singer, with contestants hoping to follow in the footsteps of season 1’s Masked Dancer winner, Olympic gymnast, Louis Smith.

Onomatopoeia, Scissors and Pearly King are through to the final
