Alesha Dixon is back on The X Factor 2017 as a guest judge.
The current Britain's Got Talent judge is stepping in for Sharon Osbourne at this week's auditions in Edinburgh.
A spokesperson for The X Factor explained: “Unfortunately, Sharon is suffering from niggling back problems following surgery earlier in the year and will be unable to take part in the Edinburgh auditions.
"Alesha will be guest judging on the panel today.”
Alesha tweeted from behind the scenes this afternoon: "Back in the chair! ❌Factor Edinburgh auditions today!"
It's the second time that Alesha has been called upon this year, replacing Nicole Scherzinger on the panel just last week.
Alesha was standing in for Nicole who was unable to make auditions in Manchester due to a 'diary clash'.
A source told The Sun newspaper: “Everyone is gutted that Nicole won’t be joining them, but Alesha has a wealth of experience from her role on BGT and her own pop career so will do a great job filling in.”
A spokesperson for The X Factor confirmed: “Alesha is guest-judging for the first day of the Manchester auditions as Nicole is unable to film that day due to a previous diary commitment.”
Joining Alesha, Nicole and Sharon on the panel this year are Simon Cowell and Louis Walsh.
Minus the guest judges, this year is the first time since between 2008 and 2010 that the regular panel has remained the same between series.
Dermot O'Leary will be back to host the show while ITV2 spin-off Xtra Factor has been axed.
The X Factor 2017 will start on ITV later this year with the air date usually at the end of August.
