X Factor stars One Direction have already pre-recorded their live performance for this week's results show.
The former X Factor finalists, who finished third in the series two years ago, returned to the stage ahead of the release of their new album.
The group performed their new single, Little Things, the second to be taken from their new album Take Me Home, which is out in November.
The group will be unable to appear live on the show this weekend as they're busy in the US, performing on the American version of the show.
This weekend will also see a performance from British singer songwriter Ed Sheeran, who will pre-record his performance on Sunday afternoon.
It means only last year's winners Little Mix will actually be performing live in the studio on Sunday evening.
The girls will be singing their new single DNA, which is out next week ahead of their album of the same name.
The upcoming live shows will also see performances from Xtra Factor's Olly Murs and X Factor judge Tulisa Contostavlos.
The X Factor continues with its live shows this weekend with a Best Of British theme.
