TV presenter Anthea Turner has also been confirmed for the show, along with retired rugby player (and Celebrity Big Brother housemate) Gareth Thomas and Olympians Beth Tweddle (gymnastics) and Luke Campbell (boxing).
The soap world will be represented by Coronation Street's Samia Ghadi (Maria Connor) and ex-EastEnders star Matt Lapinskas (Anthony Moon).
And the show appears to have become the first reality TV show to feature a real-life baroness - in the form of Baroness King of Bow - aka Labour politician Oona King.
Comic Joe Pasquale and TV personality Keith Chegwin complete the line-up.
And there's also a change on the judging panel, with Louis Spence pirouetting off to be replaced by the show's prodigal son and "Mr Nasty" Jason Gardiner.
