Louis Tomlinson's new single is a tribute to his late mother.

Johannah Deakin, 42, passed away this week after a secret battle with leukaemia and her son Louis's new song, a collaboration with DJ Steve Aoki, called 'Just Hold On', features some poignant lyrics, which are believed to be dedicated to his beloved mother.

On the track, Louis sings: ''Until it's all been said / it's not over until your dying breath / So what do you want them to say when you're gone? / That you gave up or that you kept going on? What do you do when a chapter ends? / Do you close the book and never read it again? / Where do you go when your story's done? / You can be who you want or who you'll become / If it all goes wrong, darling just hold on / The sun goes down and it comes back up / The world still turns no matter what.''

After Johannah's death was announced, Steve wrote on Twitter: ''Everyone send love and strength to @Louis_Tomlinson and his family. So so sorry my brother. We're all here for u (sic).''

As well as 24-year-old Louis - who has 11-month-old son Freddie with Briana Jungwirth - Johannah was also mother to Lottie, 18, Felicite, 16, twins Daisy and Phoebe, 12, and two-year-old twins Ernest and Doris.

This is Louis' first single since One Direction went on hiatus earlier this year and Louis will perform the track on 'The X Factor' over the weekend, despite his mother's death.

According to the Mirror Online, Louis' stepfather Dan Deakin said: ''Louis had been scheduled for some time to make a surprise performance on 'The X Factor' this weekend. This was something Johannah had been looking forward to and it was her wish that this go ahead - Louis has therefore decided to proceed with this for her.''

Dan confirmed his wife's passing in a statement, which said: ''It is with immeasurable sadness that Johannah Deakin's family said goodbye to Johannah in the early hours of Wednesday 7th December 2016.

''Earlier this year Johannah was diagnosed with a very aggressive form of leukaemia that required immediate and continuous treatment.

''We respectfully request that the family are given time and space to grieve in private.''
