It's the show with a bizarre concept that's had the nation hooked, and the biggest draw for many viewers is that they can play along at home with The Masked Singer.
The secretive singing competition sees celebrities face-off against each other to sing in elaborate costumes with full face masks concealing their identities.
At the end of each episode one eliminated contestant removes their mask to reveal their true identity - and viewers have been having their say on social media about who they think each character is, from the fox to the octopus.
Footballer Peter Crouch was even driven to tweet: "I can confirm I am not a singing tree."
So far EastEnders star Patsy Palmer was unveiled as the butterfly, the chameleon was The Darkness singer Justin Hawkins, the pharaoh was unmasked as former home secretary Alan Johnson, the tree was former England footballer Teddy Sheringham and daisy was singing superstar Kelis.
Here's a guide to which celebs are still hiding behind the masks, according to viewers.
