Whenever a celebrity mentions that they're busy working on a 'mystery project' we assume they're appearing on some sort of hush-hush reality television show.

We notice our favourite celebs doing odd little things and because we're internet sleuths, we can't help but connect the dots.

And right now, all sneaky behaviour from celebs is pointing in one particular direction: An appearance on The Masked Singer Australia.

Watch the trailer for FBoy Island. Story continues after post.

The Masked Singer Australiahas officially confirmed that we will be watching another season of the weirdly popular show, where celebs dress up in elaborate costumes in the hope to fool viewers at home whilst they belt out a song or two on our tellies.

The rumour mill has been churning ever since we figured out there would be a whole new season and we can't get enough of it.

So in celebration of the show, we are going through each of the very possible celebs rumoured to be joiningThe Masked Singerthis season.

Is Charlotte Crosby onThe Masked Singer?

If you don't recall her by name, you most likely would recognise her face (or her iconic accent) as Charlotte from the UK reality hit show Geordie Shore.

Many are suggesting Charlotte has to be on the show, given she's been spotted trying to hide her identity and go incognito whilst in Sydney – the same place thatThe Masked Singeris currently being filmed.

Considering that Charlotte has already worked with the network previously, entering the jungle on behalf ofI’m A Celebrity… Get Me Out Of Here!it makes sense that she would team up with them again for a new show.

Is Brendan Fevola onThe Masked Singer?

The former AFL superstar, Brendan Fevola has been rumoured to have joined the show, and for good reason.

In an interview with Fifi Box and Nick Cody, Brendan said he was ”supposed to go to Europe next holidays,” however, had to cancel the trip because of a 'mysterious reason' he couldn’t share any details about.

This was when Fifi asked him point-blank if it was because he was doingThe Masked Singer.To which Brendan replied: "Don't ruin it."

We think this sounds pretty suspicious!

Is Andy Lee onThe Masked Singer?

One half of the iconic Hamish and Andy duo, this Aussie comedian is well known for his appearances on television, working alongside Hamish Blake and writing children's books. According to his Wikipedia page, Andy Lee has also dabbled in music and song.

This is precisely why Andy would make the ideal candidate for the show. He's not only adored by the Australian public but knows his way around a mic.

Place your bets, folks, because our money is on this man making an appearance.
