The Take That star is set to appear on this weekend's edition of the TV talent show to perform new single 'Candy'.
Robbie Williams will help mentor Rylan Clark and Union J on this weekend's edition of The X Factor.
The singer will appear on the programme as a special guest on Saturday (27th October), before performing his new single 'Candy' on Sunday night's result show (28th October).
Robbie visited the The X Factor finalists this week to share his knowledge with the talent show hopefuls.
The Take That star also posed for pictures with all of the contestants, including Rylan, who Robbie has publicly supported on Twitter during the programme.
His comments have frustrated his Take That band mate and X Factor judge Gary Barlow, who has let it be known that he is not a fan of Rylan.

The X Factor airs on ITV 1 on Saturday at 8.20pm and on Sunday at 8pm.

Released next month, the album sees Robbie team up once again with Gary Barlow, who has produced some of the songs.
