The finalists performed several original songs during their appearances on X Factor, marking a change in the show's approach this year. With the fewest votes at the freeze, Kevin Davy White bowed out of the competition in third place.
By the end of the evening, it was decided that Kevin would not progress to Sunday, much to the disappointment of many viewers. However, this year the live finals were brought forwards to avoid a clash with Strictly Come Dancing.
On Sunday, Pink performed What About Us and Beautiful Trauma, Sam Smith sang One Last Song, and 2011 winners Little Mix teamed up with CNCO for a live performance of their Top 10 collaboration Reggaeton Lento.
Host Dermot returned to close the vote for good before revealing the final result.
When Liam appeared on The X Factor to perform, he joked: 'He fancies my missus so I've got to keep an eye on him!'
This year's X Factor final weekend also saw huge performances from big-name stars.
