The Masked Singer fans are certain that they have identified iconic star Gabrielle as the singer behind Harlequin.
The mysterious character was first to take to the stage in tonight's ITV show, with the star performing a rendition of Rihanna's Diamonds.
Dressed in a striking period-style costume with an enormous gown and dramatic face mask, Harlequin went head to head against fellow masked singers Bush Baby, Seahorse, Grandfather Clock, Viking and Blob.
While the judges appeared baffled by the voice at first, viewers at home were quick to pick up on who the striking voice could be.
Many fans outed the Dreams singer on social media as the most likely Harlequin contender thanks to her 'instantly recognisable' voice.
One viewer wrote: "the masked singer on itv now harlequin must be Gabrielle."
"Harlequin has got to be Gabrielle! That voice is instantly recognisable!" added a second.
"Ok my guess for the first masked singer harlequin is Gabrielle. Her voice is very similar, the clues aren’t matching up yet, but I’m putting it out there," added a third.
"Was cooking in the kitchen so didn't know what Simon was watching. I asked him if Gabrielle was back and then spotted it was The Masked Singer, so that's my guess," wrote another.
While the judges remained in the dark about who the character could be, they admitted that they did recognise the voice.
Rita Ora, as well as several viewers at home, also suggested that Fast Car singer Tracey Chapman could be behind the costume.
It was not Harlequin's night to be revealed and the mystery singer was voted through to the next round by the judges.
However, one star did have her identity revealed in tonight's show.
The judges and viewers were left stunned when Mel B was revealed as the iconic star behind Seahorse.
She became the second star to be eliminated from the show after another pop icon, Sophie Ellis-Bextor, was sent packing last week.
