X Factor: Louis Tomlinson and Mark Ronson are guests in judges' houses
The guests for the judges' houses stage of this year's series of the X Factor have been confirmed.
Louis Tomlinson will be returning to the talent show to help Simon Cowell choose which singers from the "overs" category will make the live shows.
Nick Grimshaw will be joined by Mark Ronson - in Manchester - and Rita Ora has been paired with Meghan Trainor.
Jess Glynne completes the line-up. She'll help Cheryl Fernandez-Versini decide which of the groups go through.
There were plans to live broadcast from the judges' houses but they've now been ditched.
Bosses wanted the auditions, which are normally pre-recorded at luxury locations abroad, to be shown in real-time this year.
But for "logistical and technical reasons" that's not going to happen.
Instead, the judges' houses will be filmed beforehand but contestants won't hear who's through straight away.
The singers will then have to wait for a big live show filmed back in London where the judges will announce the finalists in front of their friends and family.
The X Factor continues with the first episode of the Six Chair Challenge on 4 October.
