Speaking to host Dermot O’Leary after her exit, Relley said: “I could have done a bit more, but I’m so glad I experienced it.”
Tonight’s show also saw the ‘X Factor’ finalists team up with Busted for a group performance of ‘Year 3000’, while John Legend and Shawn Mendes were this week’s musical guests.
Meanwhile, the Jukebox determined that next week’s theme would be - somewhat unsurprisingly - ‘Fright Night’, with the contestants taking on songs for Halloween.
‘The X Factor’ continues next Saturday at 8pm on ITV.
