Here's a run down of the X Factor 2017 contestants and songs from tonight's first bootcamp show.
This year's bootcamp is split into two parts, starting this evening with the so-called 'wall of songs' which first made its debut on last year's series.
Contestants will face a wall which has 140 pieces of paper attached.
There are a total of 35 individual songs, each appearing four times.
On host Dermot O'Leary's signal, the acts race towards the wall and fight for the song choice they want. The contestants that have chosen the same song will then group up to work on their performance of the track.
They'll then take to the stage to sing for the judges and other contestants before the panel immediately decide who to put through to the next stage, the arena auditions in front of of a live audience.
Here's a run down of tonight's contestants and their Wall of Songs song choices...
