The identity of Sloth on ITV's The Masked Singer might already be solved, according to legions of dedicated fans. Ahead of the costume-clad celebrity's second performance on Saturday, 17th January 2026, speculation has reached fever pitch, with the majority of clues pointing squarely at reality TV favourite and I'm A Celebrity... Get Me Out Of Here! winner Sam Thompson.
The Compelling Clues Pointing to Sam Thompson
During Sloth's debut, the character awoke in fitness gear, declaring a new-found love for movement and fitness. This strongly aligns with Sam Thompson's gruelling 260-mile, five-day 'Match Ball Mission' for Soccer Aid in June 2025. He travelled from London's Stamford Bridge to Manchester's Old Trafford, raising over £1.5 million for UNICEF UK despite a calf injury.
Further hints sealed the deal for viewers. A jungle scene with a mention of 'jungle juice' is a clear nod to I'm A Celebrity, which Sam won in 2023 before hosting the spin-off show. Another visual clue showed handcuffs in a puddle, referencing the time Sam handcuffed himself to friend Pete Wicks for an hour during a Heart Radio challenge.
The Star's Playful Social Media Response
As the theory gained momentum online, Sam Thompson himself addressed the rumours on his social media. Sharing a clip of panellist Maya Jama guessing his name, he wrote: "Looks like this is relevant again exactly a year on! apparently I'm the sloth!"
He followed this with a cheeky video of himself raising his eyebrows repeatedly into the camera, accompanied by crying-laughter emojis. This playful non-denial has only fuelled viewers' convictions that he is the celebrity behind the mask.
Why Sam Thompson Fits the Sloth Persona
Fans also argue that Sloth's boundless on-stage energy perfectly matches Sam's public persona. Thompson, who was recently diagnosed with ADHD and has spoken openly about it, is known for his vibrant, restless character. One viewer on X noted: "Sloth is bouncing round a lot which reminds me of Sam Thompson."
Another recalled Sloth's comment about always wanting to be in a boyband, linking it to Sam's well-known past desire to join the band JLS. The consensus among the fanbase appears overwhelming, with many declaring the mystery solved.
The Masked Singer continues tonight (Saturday, January 17) on ITV at 7pm, where Sloth will take to the stage once more, perhaps to confirm what the audience already believes they know.
