The Masked Singer: Every contestant who has ever been revealed on the UK show

The Masked Singer is back, with fans tuning in every Saturday night to try to guess which celebrity is behind each costume.

Comedian Joel Dommett has returned to host proceedings, with 13 mystery stars singing familiar songs on stage, while dressed up in an outfit obscuring their identity.

Guessing along with the in-studio audience and the viewers at home are the judges: Mo Gilligan, Davina McCall, Rita Ora and Jonathan Ross.

One way to help narrow things down is checking out who’s been on the series before – as it seems unlikely they’d return to the show (although not impossible).
