It's The Battle Of The Voices with Mary Byrne (The X-Factor) versus Richie Hayes (The Voice) in our second quarter final on Celebrity Bainisteoir: The Rivals. Can Mary's Carlow men rise to the occasion and take on Richie's home county Waterford team from Tramore? With our loser having to pick up the the pieces and re-emerge as the winners assistant, will it be Mary polishing Richie's boots for the semis or Richie cleaning her lads kit? In an episode complete with spying, singing, tears and an nail-biting match this one isn't over till it's over.
