Who Is Mermaid on 'The Masked Singer'? Fans Spot Major Tell-Tale Signs

The Masked Singer fans think they may have worked out the famous face behind the Mermaid costume.

The theme for Season 8, Week 4 of the Fox singing show is "Andrew Lloyd Webber Night," and the famed British composer is featuring as a special guest on the celebrity panel alongside regulars Ken Jeong, Jenny McCarthy Wahlberg, Nicole Scherzinger and Robin Thicke.

Mermaid is just one of the performers taking to the stage on the Wednesday, October 12, episode and is competing against Maize and Robogirl, whose identities are also a mystery.

In a preview clip for Webber's episode, released exclusively to Newsweek, the 74-year-old musical legend, who is the man behind musicals such as The Phantom of the Opera and Cats, can be seen discussing the identity of Mermaid with the other judges.

Webber guesses that the star could be Gloria Estefan, while Jeong believes the clues point to the performer being Cher.

Long-time host Nick Cannon, who recently welcomed his 10th child, can be seen looking shocked by Jeong's suggestion in the footage, and Webber also disagrees, saying the Mermaid is not Cher.

While Webber and Jeong gave their guesses in the preview clip, fans have made their own predictions ahead of the episode.

One viewer took to social media to say that they believe the Mermaid may be either Chloe or Halle Bailey.

The musical sisters, who recently starred as guest judges on Making the Cut, are famous for their duets, although Chloe has recently been releasing her own, solo music.

Halle is also set to play Ariel in the 2023 live action version of The Little Mermaid, which the Mermaid costume could be a huge nod toward.

Posting on social media to give their guess, one fan wrote: "My Guesses for the Masked Singer S8E4 (Andrew Lloyd Webber Night)

Maize - Melora Hardin
Mermaid - Chloe Or Halle
Robogirl - Kaitlyn Bristowe."

After the show posted the Mermaid's X-Ray clue on YouTube, a seashell, others commented to question whether it could be Tia Mowry.

Tia's twin sister, Tamera Mowry, appeared on The Masked Singer in Season 5, in 2021, dressed in the Seashell costume.

So far on The Masked Singer Season 8, William Shatner, Montell Jordan, Chris Kirkpatrick, Eric Idle, Jeff Dunham, Daymond John, and The Brady Bunch stars Mike Lookinland, Christopher Knight and Barry Williams have been revealed as the voices behind the masks.

In previous seasons only one contestant has been unmasked per week, but this time around the celebrities have been divided into groups and compete within their cohort to be crowned King or Queen, with only one performer making it through to the next week unmasked.

The costumes still to come on The Masked Singer Season 8 are Avocado, Beetle, Bride, Lambs, Milkshake, Scarecrow, Sir Bugaboo, Venus Fly Trap and Walrus.

The show's executive producer, Craig Plestis, recently revealed that this season the costumes are actually clues for the identities of the performers.

He told Entertainment Weekly: "Especially for certain ones like Venus Fly Trap, that costume is a clue. This season, all these costumes, there's a real reason why each celebrity is in each costume."

It has also been confirmed that the Season 8 contestants boast a combined 32 Grammy nominations, 16 Emmy wins, eight gold albums, four Golden Globe nominations, 42 books, ten Teen Choice Awards, and five Stars on the Hollywood Walk of Fame.

The Masked Singer airs Wednesday nights at 8 p.m. ET on Fox.
