Members of One Direction reunited to support Louis Tomlinson as he sang on The X Factor just days after the death of his mother.

Louis has admitted that performing his new single Just Hold On during the final was "harder than I ever imagined".

Johannah Deakin died on Wednesday at the age of 43 after a battle with leukaemia, but Loius's bandmate Harry Styles was on hand to lend support as he took the stage in her honour.

Harry was photographed backstage with Olympian and former I'm A Celebrity contestant Sam Quek during the live final.

Fellow One Direction stars Liam Payne and Niall Horan were later pictured at Louis's celebration at a nightclub with his family.

The One Direction star has said his mother would have been "proud" to see him perform the track.

Louis, 24, thanked his fans and Steve Aoki - the US DJ he collaborated with for his latest record - for their support, on Twitter.

Last August, One Direction announced they would be going on a one-year hiatus after their Up All Night tour - but there has not yet been any indication of if or when that hiatus will end.
