The Masked Singer viewers are '100% sure' they have figured out Teeth's secret identity and they think it's a beloved sitcom actor.
Fans have been scratching their heads to solve the riddle since its first appearance on Saturday's episode - and are now convinced it's Inbetweeners star James Buckley.
The English actor - who is also a musician and podcaster - is well-remembered for playing Jay Cartwright in the E4 sitcom from 2008 to 2010.
Viewers of the hit ITV show flooded X sharing theories on which celebrity's face could be behind the mask - with many betting on Alan Carr, Rylan Clark, Alex Scott, and more.
But ultimately, many of them came to the conclusion it could now be James, 37 - with some speculating they were '100% sure' of the theory, writing on the platform:
'Watching The Masked singer and I reckon Teeth is James Buckley. Putting this out there now ‘cause I’m wrong a lot of the time but I’m so sure LOL';

The ITV show made its highly-anticipated return on Saturday, with 12 famous faces donning extravagant costumes to entertain the nation.
The sixth season's judging panel included Mo Gilligan and Jonathan Ross, with Maya Jama and Sir Mo Farah joining as special guests.
Presenter Joel Dommett kicked off the episode by asking Maya who she wanted to see perform first and she selected Teeth.
From clues such as 'I've always been a big mouth' and 'I've bitten off more than I can chew' to 'I know how to tackle the Masked Singer' and 'going for gold', theories began swirling at who is behind the mask.
Teeth later took to the stage to perform a rendition of (Is This The Way To) Amarillo by Tony Christie and shared the riddle: 'I've been schooled in variety, I have lots in the mix, the way I perform knocks the audience for six.'

Following the performance and a series of intriguing clues, the celebrity panelists began making their guesses.
Maya suggested Rob Beckett might be behind the mask, while Jonathan leaned towards Rylan Clark or Alan Carr.
Davina believed it could be Alex Scott, and Mo threw out the name Jimmy Bullard.
As Davina insisted that 'Teeth is a woman,' viewers at home took to X, formerly Twitter, to share their own theories.
They said: 'Teeth is definitely Alan Carr,'
'Teeth is definitely alan carr #chattyman #maskedsinger,'
'Either Emma Bunton or Nicole Appleton is Tattoo Snail is Emma Willis. Teeth is Alan Carr. I think comedian Harry Hill Kingfisher - I recognise his voice!'
'Thought teeth could be Alan carr but I'm now not sure,'

Elsewhere in the programme, it was the identity of Giant Joel was finally revealed, leaving fans shocked, however it seems Maya Jama had already spoiled the surprise.
Saturday's episode kicked off by unmasking Sir Mo Farah as the star posing as host Joel Dommett's doppelganger.
The character has been teased since the end of the Christmas special, which aired on Boxing Day.
Mo Gilligan guessed it was Mark Wright, while Davina McCall and Maya Jama went for Ant and Dec, but it was Jonathan Ross who got it right, by guessing it was the Olympic legend.
However, earlier in the day Maya appeared to accidentally let Giant Joel's identity slip as she took to Instagram with a selection of snaps from her first episode on the ITV show.
Posing in a selfie with Mo, one fan appeared to clock on as they warned the panelist, writing: 'The 6th one… you may wish to delete that.'
Although, Maya made sure to confirm that it was public knowledge that Mo was going to be a guest panelist.

Joel also revealed that his wife Hannah Cooper has said he is not allowed to keep the costume following the show as they don't have space.
He said: 'My wife has said that I’m not allowed to keep it because we don’t have space, so I have told her that we need to buy a marginally bigger house.
'Maybe we can turn it upside down and turn it into a really cool laundry bin or something.'
The presenter revealed that he has only shown Hannah the doppelganger and is 'excited' for the rest of his family to see it on the show.
He added: 'I actually haven’t shown my family yet! I’m excited for them to see it. The only thing weirder than watching your son on the telly is watching a big version of your son on telly standing next to your son on telly!'
It comes after Joel revealed the awkward blunder he made when Maya Jama first joined the judging panel on The Masked Singer.
The show host, 39, said viewers should brace themselves for 'twists and turns' as the new series of episodes are set to air, adding that he even saw one contestant storm off the stage.
Series three, which aired on Saturday, January, 4, 2025 at 7pm on ITV1, was also the first time fans saw Maya's debut as a panelist on the show.

Opening up on what it was like to film with the Love Island host, 30, Joel told The Sun he made one gaffe that made him 'feel really bad'.
Explaining that he doesn't really keep up with gossip, the presenter explained: 'I remember, during the recording, I kept on singing a Stormzy song and then I felt really bad about it.
'I've got this song in my head, I can't stop singing it, then someone sort of dragged me aside and said, 'That's someone that just broke up'.
Stormzy and Maya announced their shock split in July 2024 after taking to Instagram with a joint statement stating: 'We fell madly in love in 2014, broke up in 2019, and then spent five years manoeuvring life apart.
They confirmed the breakup was 'final' after previously going their separate ways following a five year relationship in 2019 and reconnecting in August 2023.
