Auditions in Manchester kick off today, which is two days later than planned, as they were postponed due to the death of Simon Cowell's mother, Julie.
Now with auditions happening on Wednesday and Thursday, it has been revealed that 'Shine Ya Light' singer Rita will be unable to make the 1pm start on Thursday due to prior engagements in Paris.
Now it has been decided that she will sit the whole day out, and a source told The Mirror that Tulisa cold temporarily fill in for Rita.
"When the new dates were arranged, it was hoped she would get back in time for Thursday's auditions," said the source. "But logistically it just can't work."
A spokesperson for X Factor also confirmed to the newspaper: "Rita obviously wanted to be there but it is just unfortunate that with the change in filming dates there is an issue.
"We will go ahead either with Simon, Cheryl Fernandez-Versini and Nick Grimshaw, or drafting in the guest judge."
Rita isn't the only one who will miss a day of filming, as Caroline Flack will also miss a session as she will have to jet off to Majorca to film Love Island, so co-host Olly Murs will have to present it on her own.
