Robobunny appeared to confirm their identity on The Masked Singer UK on Saturday night, with fans now convinced they have solved the case.
After weeks of speculating, the latest clues appeared to hint just who was hiding under the mask.
New clues included being part of a huge family, singing gospel and being possibly mistaken for a woman with their vocals.
There was also the initials 'M' and 'A' on a pair of boxing gloves, while the star performed to Dynamite by BTS.
Viewers quickly believed they had rumbled who it was, and decided Robobunny was none other than Westlife singer Mark Feehily.
Taking to Twitter after the latest performance and clues, fans confirmed they were set on this being the star behind the mask.
One fan said: "Westlife did another song called Dynamite, Robobunny is too easy to guess at this point."
Another said: "Robobunny is Mark Feehily from Westlife."
A third added: "Still say robobunny is @MarkusFeehily #maskedsinger (westlife has a song called dynamite)."
Another said: "'Dynamite' is also a Westlife Song DEFINITELY MARK FEEHILY."
Robobunny 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.
