Robbie Williams is leaving the X factor and giving up his judge's seat this week.
The singer is going back on tour for the next couple of weeks, so Chic frontman, Nile Rogers, will replace him and takeover the mentoring of his group.
This week's show will be Robbie's last show before he jets off for his gig in Chile on Monday.
According to the Irish Mirror, it will be pre-recorded on Saturday night to allow Robbie take part.
He will be in South America for the next couple of weeks and will miss at least another two live shows.
Ahead of Robbie's departure, Nile has already spent time with the contestants.
Nile will appear in this weekend's show as well as next Saturday and Sunday, but it has yet to be confirmed whether he will be there for a third show.
