Jessie J, Sir Tom Jones, Danny O'Donoghue and will.i.am completed their teams of ten hopefuls in Saturday night's (April 14) final Blind Auditions episode.
The Battle Round stage of the competition will see the contestants take part in a sing-off against each other in a boxing ring-style stage, before the coaches whittle their teams down to five each.
Match-ups include Ruth Brown taking on Deniece Pearson for Sir Tom Jones and Jaz Ellington battling Jay Norton for will.i.am's team.
The Voice UK's Battle Rounds air next weekend with a double bill on Saturday and Sunday on BBC One.
