LOS ANGELES, CALIFORNIA: FOX has unveiled 9 theme nights names for 'The Masked Singer' Season 10. The current season's theme night titles change from those from the previous season.

The theme nights for 'The Masked Singer' Season 10 are 'Trolls', 'Harry Potter', Elton John, NFL, One Hit Wonders, and more, influencing songs, costumes, celebrity guests, and set design.

'The Masked Singer' Season 10 celebrated its 10th anniversary with a kickoff episode on September 10. After a week's break, the remaining episodes of the new season will resume their normal release schedule.

A look at 'The Masked Singer' Season 10's new format

'The Masked Singer' Season 10 will feature an all-new format with three groups and special Battle Royale semi-final episodes. Season 10 will have 16 contestants WHO will be divided into three groups.

Each of the groups will be seen competing in the semifinal matches at some point during the competition, just like in the Battle Royale format. Toward the conclusion, the final three finalists will be shown singing the same song.

The song will reportedly be performed by a surprise disguised performer, according to The Sun.

In order to safeguard their identities, masked singers will not be permitted to socialize backstage or watch each other perform, according to additional regulations implemented in Season 10 of "The Masked Singer."

The judges have the authority to ring the Ding Dong Keep It On bell to prevent the elimination of one contender and send that person straight to the grand finale.

The bell, however, can only be used in a Battle Royal round only once during the whole season.

The Sun reports that the song will be revealed by a surprise masked singer performing it.

What are the new 'The Masked Singer' Season 10 costumes?

Season 10 of 'The Masked Singer' will include a total of 16 mask-wearing performers. Cow, Donut, Anteater, Hawk, Hibiscus, and S'More are the titles of the costumes.

Cuddle Monster, Sea Monster, Royal Hen, Pickle, Husky, Gazelle, Duck, Diver, Cocktail Tai, and Candle are the other masked singers who have been previewed by FOX.

'The Masked Singer' Season 10: Demi Lovato unmasked as Anonymouse

In the kickoff episode of 'The Masked Singer' Season 10, Anonymouse's mask was uncovered and the singer was none other than Demi Lovato.

The masked singer sang 'What About Love' by Heart. For Anonymouse, no hint package was previously made public. But after hearing her sing, the panelists realized that she was a skilled performer.

Nicole Scherzinger said, "You are a pistol and you just blew the roof off this place!" Anonymouse's first clue was, "Well, just like Michelle Obama, Oprah, and Angelina Jolie, I’m on one special list, TIME’s 100."

This leads the panelists to guess Miley Cyrus, Alicia Keys, Christina Aguilera, Ariana Grande, and Lady Gaga.

Anonymouse revealed more clues about her personality by stating, "Men in Black." She continued, "My acting career cemented me as one talented mouse," and she included a picture of Nick Jonas. This made Demi's identity quite evident.

Except for Ken Jeong, every panelist identified the vocalist as being Demi, and they were all correct.

'The Masked Singer' Season 10 releases every Wednesday from September 27 onwards at 8 pm ET on FOX.
