The Masked Singer fans convinced they've uncovered Wolf's identity 'within minutes'
Viewers of The Masked Singer on ITV believe they have already identified the celebrity behind Wolf. Many are convinced the mystery singer is Marti Pellow, the 58-year-old frontman of Wet Wet Wet.
After his latest performance, social media was flooded with fans claiming they recognised his voice. Some said they figured it out as soon as Wolf sang for the first time.
Vocal clues point to Marti Pellow
Wolf's rendition of Birds of a Feather by Billie Eilish last week had fans speculating. His latest performance of Rebel Yell by Billy Idol has only strengthened their theory.
One viewer wrote: "It's Marti Pellow! I can hear Marti now!" Another added: "He's disguising his voice well, but based on previous performances, it's still got to be Marti Pellow."

Wolf's clue package adds to the theory

Another clue was a tartan picnic blanket. Fans have linked this to Marti's Scottish roots.
Despite the strong Marti Pellow theory, others have different guesses.

Wolf's performance gets a big reaction
Regardless of who Wolf is, his latest rock-inspired performance impressed the panel. The judges were up on their feet as he delivered a high-energy rendition of Rebel Yell.
Maya was particularly enthusiastic, shouting "rock on" as the audience cheered.
Is Marti Pellow behind the mask?
Marti has been in the spotlight recently, teaming up with Lorraine Kelly for a special music project. They recorded Love Is All Around with the Change and Check Choir, celebrating 30 years since the hit topped the charts.
Whether Wolf turns out to be Marti or not, fans will have to wait for the big reveal.
