MASKED Singer fans are convinced Wolf is a legendary Scottish pop star after a cryptic clue.
The hit show returned to screens yesterday with new judge Maya Jama, 30, joining the panel alongside Davina McCall, 57, Jonathan Ross, 64, and Mo Gilligan, 36.
ITV's secret singing battle - fronted by Joel Dommett - has already unmasked two huge stars with GMB anchor Kate Garraway revealed as Spag Bol and Bake Off judge Prue Leith behind the Pegasus veil.
And eagle-eyed viewers reckon they've figured out Wolf's identity after the performer belted out David Bowie's Let's Dance.
The masked musician, wearing leather boots and a waistcoat, teased viewers with a trail of cryptic clues.
He said: "You wanna know more about little old me, if the three little pigs had listened to my advice no huffing or puffing would've blown those houses down.
"As a wolf, I've held dominion over everything I see, wild woods, creek or cave, that's my territory."
The judging panel tried to guess who was behind the disguise and suggested David Tennant, Jason Donovan, Simon Le Bon, and Bono.
But armchair sleuths rushed online, speculating that Wet Wet Wet frontman Marti Pellow, 59, had swapped the studio for the Masked Singer stage.
One guessed: "Wolf is 100,000 per cent Marti Pellow, so many of his vocal notes in that performance.”

Another added: “That’s Marti Pellow as Wolf. I’m telling you, I know his voice anywhere.”
A third chimed in: “I’ve been a fan of Marti since I was 13 and would recognise that voice anywhere.”
It comes after Marti joined forces with telly fave Lorraine Kelly to record a new version of Wet Wet Wet's Love Is All Around with the Change and Check Choir.
Meanwhile Masked Singer fans are also convinced that Teeth is a cheeky chappy footballer and I’m A Celeb star.
