The trio of boybands will be special guests on the Sunday, November 14 show, Simon Cowell revealed on last night's Xtra Factor.
Speaking to Konnie Huq during the judges Q&A session, Cowell let slip that all three acts would be on the same programme. A fully-reunited Take That will be performing their comeback single with Robbie Williams, 'The Flood', Louis Walsh's Westlife will return once again to the show to sing their latest single 'Safe', while 2008 runners-up JLS are promoting their new track 'Love You More'.
All three boybands will be competing over the next month for the number one spot, so their performances on the show will be seen as crucial in indicating how they might fare in a chart battle.
Next Sunday's results show will feature appearances from Kylie Minogue and series two X Factor winner Shayne Ward.
