The Boys and Groups will sing on The X Factor on Saturday night.
The Girls and Overs will then follow on Sunday evening, in a change to last week's line up.
14 finalists remain in the competition after the opening weekend saw two contestants given the boot.
At least two more acts are expected to leave this weekend as the finalists sing over Saturday and Sunday night once again in their categories.
The Boys and Groups are first up on Saturday while the Girls and Overs will sing on the Sunday evening with this week's Viva Latino theme.
At the end of each live show, a public vote will decide which one act is 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 a trip to New York to watch P!nk in concert before meeting her backstage, which was won by Grace Davies after her sing-off against Rak-Su.
Meanwhile, it was Boys' Spencer Sutherland and Overs' Talia Dean who got the boot.
The pair's exit leaves a total of 14 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, Sam Black and wildcard Leon Mallett and Nicole Scherzinger's Overs Kevin Davy White, Matt Linnen and Tracy Leanne Jefford.
The X Factor 2017 continues this Saturday at 8:20PM and Sunday night at 7:05PM on ITV.
Guest stars will be BGT winner Tokio Myers on the Saturday and and Rita Ora on the Sunday.
