LIVE: Masked Singer 2020: Masked Singer star revealed as Katie Noonan

Not a single judge could pick tonight's unmasked celeb, The Sloth. It turned out to be a star with one of the most distinctive voices in the country.

Aussie music icon and five-time ARIA winner Katie Noonan has revealed herself as the Sloth.

Following on from Monday's unmasking of Christine Anu - who was guessed by everyone in Australia bar the judging panel - Noonan left the competition to embarrassed judges, who couldn't pick her voice from beneath the mask either.

Throughout the episode, they had locked in guesses of Mahalia Barnes and Sia - certain it was indeed a professional musician.

As Noonan, formerly of Aussie rock band George, unmasked, Hughesy shook his head, sheepishly admitting he's a huge fan.

So far, cricketing legend Michael Bevan has been revealed, with international sporting legend Mark Philippoussis unmasked during the season premiere.
