While none of the contestants is looking forward to be booted out of the show, they'll only be heading back to their friends and family. For soldier Jonjo Kerr, it'll be off to the front line in Afghanistan if his bid for X Factor fame does not work out.
The 27-year-old from Lancashire has been given special permission by the Army to star in the show.
He said: "I don't have to watch TV or open a magazine to see heroes, I can just go to work."
He added: "The battalion is due to go on tour next year in Afghanistan and, if this doesn't work out, I'll go back to proper work - full-time duty."
He added: "If one person I don't know picks up the phone to vote for me or if one person tweets me, I've had so many messages on Twitter and Facebook from people I've never met in my life, but they're just genuinely giving me really nice messages."
Jonjo and his fellow X Factor finalists will perform live for the first time on tonight's show.
