But the spoiler is enough to convince viewers that the wolf is in fact Mills, stating they recognise the former Australian Idol star’s distinctive voice – with even Bachelorette star Georgia Love tweeting her predictions.
The Masked Singer sees 12 celebrities face off against each other as they perform anonymously in elaborate costumes (including a lion, dragon, octopus, monster, wolf, unicorn and prawn costume), but some viewers have been left confused around one major detail - whether or not the masked singers are actually singing "live".
And while the official stance from Channel 10 is that the artists behind the costumes are singing live, fans aren’t entirely convinced.
“So im confused - how is this live?” wrote one user.
“Hey #MaskedSingerAU, why give mics when they're masked, they're surely not singing live then?!” tweeted another.
