X Factor finalists, from left, Perrie Edwards, Leigh-Anne Pinnock, Jesy Nelson and Jade Thirlwall, of girl band Little Mix, pose with their mentor Tulisa Contostavlos, centre, during photo call ahead of this weekend’s final.
Judges Kelly Rowland, Ms Contostavlos and Gary Barlow are set 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.
