Viewers of ITV's hit show The Masked Singer UK are buzzing with the conviction that they have finally identified the celebrity behind the elaborate Moth costume. Following the latest performance on Saturday 17th January 2026, a strong consensus has emerged on social media, pointing the finger squarely at Keisha Buchanan, a founding member of the iconic girl group the Sugababes.
The Clues That Gave The Game Away
During the broadcast, Moth delivered another impressive vocal performance accompanied by a fresh set of cryptic clues. These hints referenced jazz, being an artist, the word 'beehive', and a connection to Scotland. However, for many eagle-eared fans, it was the distinctive tone and delivery of the singing voice itself that proved to be the most significant giveaway.
Taking to social media platform X, viewers were quick to share their verdict. One fan stated definitively, "Moth is Deffo Keisha from Sugababes," while another praised, "Moth is Keisha from Sugababes. Her voice is fire." The certainty was palpable, with a third commenter noting, "Just from that intro Moth is 100% Keisha Buchanan from Sugababes!"
A Theory Gaining Momentum
This is not the first time this particular theory has surfaced. Keisha Buchanan's name was also heavily linked to the Moth character following its debut performance earlier in the series. The latest evidence has only served to solidify these suspicions for the show's dedicated audience.
While the leading guess remains the Sugababes star, some other viewers have speculated that the mystery singer could be another powerhouse vocalist such as Leona Lewis or Alexandra Burke, both winners of The X Factor.
Following a Legendary Unmasking
The speculation around Moth's identity comes hot on the heels of a major reveal in the previous episode. The celebrity behind the Yak costume was unmasked as Sex Pistols punk icon John Lydon (also known as Johnny Rotten), a revelation that left the panel and home audience stunned.
Many fans admitted they were completely fooled, with one writing on X, "Nope didn’t get that lol," and another tweeting, "Would never have guessed him…" True to his rebellious nature, Lydon later remarked that appearing on the show was "hardly" the highlight of his career, but he hoped his "funstar" side came across.
The Masked Singer UK continues to captivate audiences, airing on Saturdays at 7PM on ITV1 and ITVX. As the competition progresses, all eyes—and ears—will remain firmly on Moth to see if the fans' predictions are correct.
