The Overs and Groups will sing on The X Factor on Saturday night.
The Girls and Boy will then follow on Sunday evening, in a change to last week's line up.
12 finalists remain in the competition after the latest weekend saw another two contestants given the boot.
This weekend will see a another double elimination: Two more acts will leave this weekend as the finalists sing over Saturday and Sunday night once again in their categories.
The Overs and Groups are first up on Saturday while the Girls and Boys will sing on the Sunday evening with this week's George Michael theme.
At the end of each live show, a public vote will decide which acts are immediately given the boot with the bottom two sing-off axed.
Instead, the acts who top Saturday and Sunday's vote face off in a new 'prize fight' to win a special reward.
Last week the prize was studio time with a top record producer, which was won by Kevin Davy White after his sing-off against Rak-Su.
Meanwhile, it was Boys' Leon Mallett and Overs' TracyLeanne Jefford who got the boot.
The pair's exit leaves a total of 12 acts remain in the competition's final stages.
They are Simon Cowell's Groups Rak-Su, The CutKelvins, Sean and Conor Price and wildcard Jack & Joel, Sharon Osbourne's Girls Grace Davies, Rai-Elle Williams, Holly Tandy and wildcard Alisah Bonaobra.
Plus Louis Walsh's Boys Lloyd Macey and Sam Black and Nicole Scherzinger's Overs Kevin Davy White and Matt Linnen.
The X Factor 2017 continues this Saturday at 8:10PM and Sunday night at 7:30PM on ITV.
Guest stars will be One Direction's Harry Styles on the Saturday and and Paloma Faith on the Sunday.
