It's a question many viewers of The Masked Singer might have asked - how are the identities of the contestants kept a secret?
The new series of the ITV show is under way and fans are eagerly trying to guess who the contestants are. A celebrity panel of Davina McCall, Rita Ora, Jonathan Ross and Mo Gilligan make their guesses about the person under the masks each week.
So far, we have seen Ghost unmasked as Chris Kamara, while Piece of Cake turned out to be singer Lulu. The identities of the contestants are kept a secret from all until they are unveiled on the show.
