Rockhopper on The Masked Singer UK is Destiny's Child singer Michelle Williams, according to ITV viewers.
Fans believed the latest clues and vocals confirmed the identity of the character on the show, and they took to Twitter to share their theories.
The clues included a series of photos of William Shatner, William Shakespeare and Prince William - pointing viewers to the name William.
One viewer said: "Ahh the ‘Williams’ rings true to the people on Twitter saying it’s Michelle from Destiny’s Child."
Another wrote: "If you haven’t clicked that Rockhopper is Michelle Williams from Destiny’s Child from the clues tonight, I don’t know how to help you."
Another said: "If we are going through the Destiny's Child route, Bootylicious sampled Edge of Seventeen. I can't tie between the two girl bands."
A third said: "Michelle Williams from Destiny’s Child no doubt for Rockhopper."
Taking all the clues into account, one user said: "Rockhopper - Michelle Williams all the clues - all the Williams, tarot cards - destiny, the halo comment - Beyoncé."
Rockhopper 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.
