Harriet Rose is one of the very few people allowed backstage at The Masked Singer - so if anyone has seen it all, it's her.
Tonight, Moth, Conkers and Toastie will battle to become the seventh winner of the ITV series, following in the footsteps of last year's champion, Pufferfish, aka Samantha Barks.
It's been a series packed with shocks - from rapper Professor Green's surprisingly impressive vocals to John Lydon being uncharacteristically well-behaved. And according to Harriet, one final jaw-dropping reveal is still to come.
As presenter of The Masked Singer: Unmasked, Harriet waits in the wings for each celebrity as soon as they step off stage - and one unmasking in particular left her completely 'starstruck'.
She told Metro: 'I'm not telling you who I was shocked by, but I was jaw on the floor with one of the finalists. Genuinely, my jaw was on the floor and it has been with a few this series, but specifically with one. I was convinced it was someone and then my jaw hit the floor.'
This series has arguably delivered one of the most eclectic line-ups yet, with secret celebs hidden beneath ever more elaborate costumes - from Strictly's Anton Du Beke as the gracious Arctic Fox to Harry Hill as the mischievous Red Panda.
For Harriet, however, the biggest rug pull came courtesy of the noughties pop star disguised as the sassy Business Monkey.
'The biggest surprise for me was Kate Nash,' said Harriet. 'I realised on her last day, but I know Kate personally, so I was like, "Oh my God, that's Kate Nash!" because I was also a big, big fan of her. Before I knew her, I went to see her when I was like 18.'
While viewers will see the spectacle on stage during tonight's final, Harriet sees the secrecy up close. Behind the scenes, it's nothing short of a military operation to ensure identities remain hidden - from everyone, including the contestants themselves.
'I'm probably the most privy to seeing people backstage, and it is still as exciting as you'd imagine,' she says. 'You feel like you shouldn't be seeing them, which you shouldn't really and because I don't know who anyone is I'm living for the thrill of it.
'But I would say the air is not competitive. It is like the most love-filled show. These people are not there because they want to "win"; they just want to stay in and keep having fun. A lot of these celebrities are never going to grace the stage again, they're never going to dress up and be silly in this way.
'There hasn't been one person that I've ever interviewed in the history of the show, who hasn't been gutted they've left.'
Not everyone has taken elimination quite so gracefully though. One famously sore loser stormed off stage and never returned: Macy Gray. The singer was furious after being voted out in week three as Toad In The Hole - and didn't attempt to hide it.
Contestants traditionally speak to Harriet after their exit - but not Macy.
'The producers did make me run after [her] for a bit but no she wasn't up [for] having a chat. I think when adults play a fun sort of kids-style game, which is what it is, you can actually get genuinely sad. I think she was genuinely gutted, because it's actually fun.'
Thankfully, Harriet has found no shortage of willing talkers for her new podcast, By The Way... With Harriet Rose. The show was inspired by her impulsive need to tell everyone she meets that she's gay within the first five minutes, a celebration of oversharing. 'TMI is my chef's kiss,' she says.
But it wasn't always that way. The podcast is somewhat of a rebellion against the presenter she once thought she had to be - someone who felt compelled to hide her sexuality at a time when it wasn't considered 'cool' to come out in an industry that has historically been prejudiced towards the LGBTQ+ community.
Now, she says, 'cool is perceived as interesting, wonderful and beautiful and open.'
Guests, including Jade Thirlwall, Jonathan Ross and Cat Burns, follow Harriet's lead in being unapologetically unfiltered. They share the confessions they consistently slip into conversation, the rumours they want to shut down and the fears they rarely voice, sparking punchy anecdotes you won't have heard elsewhere.
Having spent years on press tours, Harriet was determined to create something different.
'I was doing a lot of junkets and interviews and I'm friends with some of the people I interview. Over the years, we've met, become friends, and we talk in real life outside of work, and I know stuff about them that's really interesting.
'I love to walk away from an interview and think, "No one is going to know that about Stephen Graham; no one is going to know that about Rihanna," so I wanted to find a safe space where people can come to talk about something they actually really want to talk about so listeners learn something about their favourite celebrity no one else knows.'
And the revelations so far?
'I've got one person who talked DJing for John Lennon, another person who missed a call from Noel Gallagher because she's scared of answering the phone. Jade clears up a very funny video that everybody misconstrued as her being on drugs from years ago.
'In my career, multiple times, people have asked me to do things that I simply will never do to get something out of someone. Why would I want to do that? So to me, the joy comes out of people knowing they're just going to have a nice time.'
The Masked Singer final airs tonight at 7pm on ITV. By The Way... With Harriet Rose launches Thursday, February 19.
