The Masked Singer spoilers
Meet the unmasked singers so far below...

Also in the semi-final, Fox was unmasked as star of stage and screen, Denise Van Outen.
The actress, who has appeared in the West End and Broadway, said she relished the opportunity to do something outside of her comfort zone.
At the end of the opening show, it was revealed that the identity of Butterfly was actress Patsy Palmer, best known for her role of Bianca Jackson on BBC soap EastEnders.
After her exit, Patsy said: "I loved it, the costume designers are so talented and I loved being a Butterfly. I love singing in general (not that I’m any good) but it's an extremely uplifting thing to do. I love music, it's a total passion of mine (I DJ) so I’m constantly playing music.
"To be able to get on a stage that size was a dream too although I must say I was really nervous."
At the end of the second show, it was revealed that the identity of Pharaoh was politician Alan Johnson, who previously served as Home Secretary for the Labour party.
Asked why he signed up for the show, Alan Johnson said: "Because it was so weird and wacky", and admitted that going out in the first round was the toughest part of the process.
At the end of the third show, it was revealed that the identity of Chameleon was Justin Hawkins, frontman of The Darkness.
Asked why he signed up for the show, Justin said: "I wanted to take part in something that would be slightly surreal, and the secrecy made it a very exciting. Like having an extra-musical affair.
"I was reluctant to commit to the recordings because I was supposed to be best man at a wedding in Australia, but it was too good to turn down. Haha!"
He added: "The toughest part of the process was learning relatively modern songs. I’m not fond of new music, so I had to force myself to assimilate inferior compositions... Plus it was difficult to sing from within a helmet!"
At the end of the fourth show, it was revealed that the identity of Tree was former England footballer Teddy Sheringham.
After his exit, Teddy said: "I'm sure there will be a lot of people saying my singing is very wooden, I'll take that.
"In a sadistic kind of way I really enjoyed my Masked Singer experience... not sure I'd want to do it again, but I enjoyed it."
He added: "I've been asked to do everything over the years but always declined. I saw the show that aired in the States and thought I'd love to do that for my kids."
At the end of the fifth show, it was revealed that the identity of Daisy was American singer, songwriter and chef Kelis.
After her exit, Kelis said: "It was fun. If I were to do it all over again, I definitely would have done something a little more dramatic or elaborate because that’s me, but it was cute and definitely did its job!
"The two weeks of filming was tough. Wearing a mask everyday. No talking. Staying in your trailer. That was definitely a first. LOL."
Asked what made her decide to take on the challenge, Kelis shared: "My two boys. They really were the main reason. They thought it was the coolest thing in the world. So I did it for them."
In the sixth show, Duck was revealed as singer, songwriter Skin lead singer of rock band Skunk Anansie.
Skin said: "It was really fun jumping into a completely different character and using it to portray a sillier side of myself that the public rarely get to see, but it was quite difficult to sing in so that held me back a little!"
Asked why she took on the challenge, Skin replied: "Because it’s bonkers, challenging, weird as hell, unpredictable and a laff! All the things I love!"
She added of her time on the show: "Trying to dance was madness! Lol My song choices really put me out of my comfort zone which was the reason I chose them, when you’re dressed as a giant Duck there are many songs that just don’t work so there was a lot of trial and error!"
At the end of episode six, Unicorn was revealed to be singing superstar Jake Sears from chart topping band Scissor Sisters.
Jake said: "I loved my costume, especially the face, because I loved how lifelike the eyes were. Also, it was such a mobile costume which I appreciated because I love to move so much when I perform. I found the peplum midsection though made it difficult to shake my hips. "
He said of singing up: "I knew that this would be one of the most unique situations I would ever be in, and I was correct. One of the perks of what I do is sometimes getting to have very unique experiences, this was no exception.
"Also, I love masks, love ridiculous costumes, I love entertaining at all cost! I love singing. It was a no-brainer."
