The Masked Singer UK viewers think they know who Firework is on the ITV series.
Viewers suspected it was Pixie Lott under the mask, during the latest episode.
Firework dropped a new song as well as a bunch of new clues, teasing their identity.
As the panel began guessing who they thought was under the mask, viewers took to Twitter with their own suspicions.
From socks featuring foxes to riddles and rhymes, and a random array of letters which spelled out 'Albert' in a square box, the clues suggested it could be someone with a link to EastEnders - after the reference of a "hard man" too.
She also performed Kids by singers Robbie Williams and Kylie Minogue - while fans believed the EastEnders clues were a red herring.
Taking to Twitter, fans began claiming it was The Voice Kids coach Pixie Lott behind the mask, as others suggested Dani Dyer.
One fan said: "Firework is @PixieLott kids is reference to the voice kids she is a judge on."
Another agreed: "Firework is Pixie Lott," as a third added: "Firework has to be Pixie Lott - she judges the voices kids and she’s singing a song called kids."
A fourth wrote: "Fireworks - pixie Lott? The song is called kids and she’s a judge on the voice kids."
Firework performed as one of eight contestants competing to stay on the show, ahead of the next elimination.
Last week, Pat Cash became the fourth celebrity to be unmasked as it was revealed he was Bagpipes on the show.
Panellist Jonathan Ross was convinced it was fellow tennis player John McEnroe behind the mask, and was stunned to find out he was wrong.
Will Young was third to be unveiled a week earlier, after fans correctly worked out he was Lionfish on the ITV series.
This followed the first two eliminations of the series earlier in the month, with Loose Women star Gloria Hunniford being unmasked as Snow Leopard in episode two, and singer Heather Small revealed to be Chandelier in the very first episode.
Viewers have been predicting for weeks who the mystery celebrities are underneath the remaining costumes.
On Saturday nigh’s show, it was Panda, Poodle, Firework, Mushroom, Doughnuts, Traffic Cone, Rockhopper and Robobunny taking to the stage.
As ever, Jonathan and his fellow panellists Rita Ora, Mo Gilligan and Davina McCall took it in turns to predict who was under the masks, as host Joel Dommett also tried to work it all out.
The Masked Singer UK airs Saturdays at 7pm on ITV.
