Taylor Swift has been announced as one of the first performers for the 2014 X Factor live shows.
The internationally acclaimed pop star, whose fifth album 1989 will be released on 27 October, will perform her new single Shake It Off during Sunday's live show.
The 24-year-old singer has performed on the live show for the last two years, singing her hit single We Are Never Getting Back Together in 2012, and The Last Time in 2013.
Also on Sunday's live show will be RnB star Pharrell Williams, who will perform new tune Gust Of Wind. After several weeks of auditions, boot camps, and time spent at judge's houses, the 12 finalists will get to perform live for the British public on Saturday.
During the final pre-recorded show on Sunday Simon Cowell decided that the Over 25s groups would consist of Jay James, Ben Haenow and Fleur East while Cheryl Cole's Girls were whittled down to Lauren Platt, Stephanie Nala and Chloe Jasmine. Meanwhile, Louis Walsh's Groups are Blonde Electric, The New Boy Band and Only The Young while Mel B decided that Andrea Faustini, Jack Quickenden and Paul Akister would make her final three acts.
With the Boys' group proving to be firm favourites to win, the pressure is on for the hopefuls to impress at the live shows next Saturday.
