The coaches' ten remaining acts will perform in Saturday's episode, before one person from each team is voted off in Sunday's pre-recorded results show, according to a post on the talent contest's official blog.
Meanwhile, all four panellists - Will, Tom, Jessie J and Danny O'Donoghue - will take to the stage again in the Saturday show, singing U2 hit 'Beautiful Day'.
They previously performed The Black Eyed Peas' 'I Gotta Feeling' as an opener for the first Blind Auditions episode.
Earlier this week it was announced that 'Video Games' singer Lana Del Rey will also make a guest appearance.
