Judges to perform with acts in X Factor final
The X Factor finalists look set to team up with their mentors as the series reaches its climax this weekend.
Judges Kelly Rowland, Tulisa Contostavlos and Gary Barlow are to perform with the three acts during Saturday's edition of the programme, according to reports.
Marcus Collins, Little Mix and Amelia Lily will battle it out to be crowned the winner on Sunday night's finale.
They are said to have been rehearsing for days with members of the panel. The fourth judge, Louis Walsh, has none of his acts left in the competition.
Producers often try to pack the final with star names as an added draw for viewers.
This year's competition will end with performances by Coldplay, Leona Lewis, JLS and One Direction.
Last year the series ended with slots by Rihanna and Christina Aguilera, but the raunchy performances brought a flood of complaints and were criticised by TV regulators.
