This weekend Robbie Williams flies off to South America for his tour.
Robbie's tour was already booked when he accepted the X Factor role and bosses knew they had to work around it.
Robbie flies to Chile on Saturday night, so for the first time ever X Factor will be pre-recorded earlier in the day to allow Robbie to keep his seat this week.
On Sunday, Nile Rodgers will sit in Robbie's seat for the vote. Nile is expected to cover for Robbie for a couple of weeks. He has already met the groups this week.
Nile of course helped Louis Tomlinson at his judges house earlier this year.
This weekend the guest performers on Sunday are Liam Payne and James Arthur who perform their new singles.
