The Masked Singer Australia is famous for tricking its viewers when it comes to the celebrities under the masks.
While some are easily recognisable because of their unique voices or signature singing styles, others are harder to pick.
The full 2021 line-up hasn't even been announced yet, but fans are already taking guesses at who will appear on the show this season.
Most of the speculation so far surrounds Mullet, who has been featured pretty heavily in the latest trailers.
We heard him sing in the first teaser, then saw his mask pop off in the second, almost revealing his identity.
Now presenter Chrissie Swan thinks she's figured out who's under the bizarre fish mask Mullet wears.
Chatting about the latest season of The Masked Singer on radio show Chrissie, Sam & Browny this morning, she revealed her guess.
"Lindsey Lohan is not in it sadly, but the Mullet mask is in it and we've already guessed," she teased.
"It's Dylan Lewis! It's Dylan Lewis!"
Chrissie went on to reveal a second identity, adding: "Em Rusciano's in it as well, but I don't know what character she is."
She confessed anchor Dean 'Deano' Thomas was the one to figure out Dylan Lewis is the person supposedly under the Mullet mask.
If you don't already know, Dylan Lewis is a musician and Aussie TV and radio host best known for winning Celebrity Big Brother in 2002.
He worked as a presenter for Nova from 2006 until 2012, before moving to a co-hosting gig on the co-hosted the Lewis & Lowe breakfast show for Nova in Adelaide.
In 2020 he moved to ABC, where he is currently the weekend Double J morning presenter.
But is he really behind the Mullet mask? Fans don't seem convinced.
Guesses about Mullet's identity have been flooding in on social media, with fans throwing out a whole host of celebrity names.
Some claim it's former AFL star Berto "Dipper" DiPierdomenico, who was known for his signature mullet hairstyle.
Other have guessed it may be Jimmy Barnes or even former Bachelor Nick 'Honey Badger' Cummins.
It looks like we'll just have to wait and see if we want to find out who is really under the mask.
The new season of The Masked Singer Australia premieres on Monday, September 13 at 7.30pm.
