The Masked Singer has had audiences hooked since it premiered on Monday, and with two of the singers already unmasked, one of them has been leaking secrets about the show.
Gretel Killeen was revealed to be the Octopus on Monday night, and has since appeared on The Project, accusing one of its panel of secretly appearing on the show.

The former Big Brother host was a guest on the Channel 10 show on Tuesday night, where she was grilled about the process of the show by Carrie Bickmore.
Talking of her co-star Waleed Aly, Carrie joked: "You wouldn't know whether it's Waleed behind The Robot?"
To which Gretel replied: "I know Waleed is definitely in it."
And there are clues to confirm it.
As it turns, out Waleed formed his band Robot Child, which consisted of six members, in Melbourne back in 2008.
Gretel isn't the only one to suspect the TV presenter, as earlier this month, comedian Ed Kavalee speculated live on The Project that Waleed could be behind one of the masks — specifically the robot.
Although Waleed denied it at the time, we're not too sure!
Gretel was unmasked on Monday for her performance as The Octopus. And on Tuesday night, The Parrot's identity was revealed as cricket legend Brett Lee.
