Next Saturday (November 24), the final five acts will sing tracks from ABBA's back catalogue and songs from the Motown era.
It was revealed by The Xtra Factor hosts Caroline Flack and Olly Murs that the popular themes will return for the quarter-final of this series.
Five acts remain in the competition after tonight's (November 18) shock result, which saw the last remaining girl Ella Henderson leave the show. Three of the acts - Rylan Clark, James Arthur and Jahmene Douglas - belong to Nicole Scherzinger's boys category, while Union J and Christopher Maloney complete the lineup.
It was also revealed on the ITV1 show tonight that Rihanna will perform on next week's results show alongside Bruno Mars. Judge Tulisa will also take to the stage to perform her new single 'Sight of You'.
Motown Classics was a theme on last year's semi-final, with eventual winners Little Mix performing 'You Keep Me Hanging On'.
The X Factor continues next Saturday at 8pm on ITV1.
