Feehily said: "Normally I just stand there and sing," while Jonathan Ross said: "You normally sit on a stool and sing, is what you meant to say."

The boyband star added that he had taken on the challenge for his daughter: "Doing this has allowed me to explore my voice as well, but I've also spent the last two years with my baby so I've watched a lot of cartoons. This is for Layla."

He said of his Westlife costars: "I told the boys I'm just going to stay in London and chill out for a couple of days and they were like, but you've got a baby in Ireland."

Jonathan Ross joked: "You're going to have to get home or people are going to think you're having an affair."

Many of the show's fans had guessed that Robobunny was Feehily weeks ago and judge Rita Ora had also guessed his identity.

One fan tweeted: "MARK from the second i heard the voice i knew. absolute babe always & forever a westlifer."

Someone else added: "I know we all guessed it weeks ago but did any other die hard Westlife fans know that was definitely Mark just from the back of his head??"

The three finalists all sang duets with past Masked Singer contestants - Robobunny with Nicola Roberts who won series one as Queen Bee, Panda with Hedgehog, aka Jason Manford, and Mushroom with Aston Merrygold as Robin.

Joss Stone, who won series two as Sausage, returned as a guest judge for the final.

Asked how the contestants would be feeling, she said: "It's very nerve-wracking, I know that you've got a mask and nobody really knows who you are so it's fine, but this is the night you've got to take it off and you're thinking, 'oh, they're going to find out it's me!'."

The remaining two contestants Mushroom and Panda will be unmasked at the end of the show when the winner is announced.
