Since Frankie Cocozza left the show, there's been much speculation as to whether another contestant would be brought back to take his place.
It's been revealed that one out of the four acts that were kicked off the first live show will be brought back for the next programme.
The public can now vote for who they wish to perform on the night, and viewers will only find out who's coming back when they tune in.
The acts to choose from are (above: from left) Jonjo Kerr (in the over 25 category), 2 Shoes (in the groups), Amelia Lily (in the girls category) and James Michael (in the boys category).
All four acts were eliminated in the first week by their own mentors, without facing the public vote.
