The final three contestants performed for judges Maya Jama, Mo Gilligan, Davina McCall, and Jonathan Ross.
The judges were given a final opportunity to guess the masked identities.
After the show, the 80s singer took to Instagram to share that he had an “amazing time” on the ITV show.
Viewers playing at home have been guessing it was the Scottish singer for weeks.
One took to X to say: “Wolf is either Marti Pellow or Curtis Stigers based on that duet performance.”
Another commented: “Marti Pellow is surely the wolf on the Masked Singer.”
With another viewer saying: “Wolf is Marti Pellow hundred per cent.”
Not everyone was certain about Marti, one X user said: “Wolf on the masked singer for me is Alex Turner.”
