Louis Tomlinson of One Direction appeared on The X Factor UK to premiere his debut solo single, "Just Hold On" - with DJ Steve Aoki - as a tribute to his mum Johannah who passed away last week after being diagnosed with a very aggressive form of leukaemia earlier this year.
Bandmates, Harry Styles, Niall Horan, and Liam Payne all reunited for the first time in a year to support Louis backstage in his dressing room at Wembley Arena - with Niall flying in overnight from New York and Liam coming from Los Angeles.
Johannah Deakin, 43, died from Leukemia on Wednesday.
"It is with immeasurable sadness that Johannah Deakin's family said goodbye to Johannah in the early hours of Wednesday, December 7," the family said in a statement. "Earlier this year Johannah was diagnosed with a very aggressive form of leukemia that required immediate and continuous treatment. We respectfully request that the family are given time and space to grieve in private."
Deakin, who was a midwife, is well known to One Direction fans and often appeared on social media with her famous son.
Tomlinson recently posted a pic of him and mother, who was lovingly known as "Jay," with the caption, "My mother looking gorgeous before the Brits earlier this year. I love you and miss you so much!"
