It's Celebrity Bainishteoir but with a twist. And a presenter in the form of Mairead Farrell. This year each celebrity is paired against a rival celebrity 'from their own world.' It's X-factor versus The Voice as singer Mary Byrne takes on Richie Hayes; the battle of UK reality TV as celebrity traveller and celebrity Big Brother winner Paddy Doherty takes on the bloke who hasn't been on UK TV in years Calum Best; the battle of the 'babes' as WAG Jessica Lawlor goes head to head with model Roz Purcell and married couple Brian Ormond and Pippa O'Connor pretend to be at war. Fans of Zig and Zag: they're being wheeled out again, this time for a 'Super Bloopers' show, which follows at 7.30pm.
