Louis Tomlinson's mother, Johannah Deakin has passed away after a battle with leukaemia.

The midwife, 42, died on Wednesday after a six month battle with the disease.

One Direction's Louis will perform on the X Factor tomorrow night in tribute to his mam – she had expressed that she wanted him to do so before she passed away.

That is going to be heartbreaking to watch.

In a statement released today from Johannah's husband Dan, he 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.

“Johannah was first and foremost a truly amazing mother to seven children – Louis (24), Lottie (18), Félicité (16), and two sets of twins, Phoebe and Daisy (12) and Ernest and Doris (2)  – whose individual talents and success are testament to the principles and beliefs she instilled in them. She was also an incredibly proud grandmother to Freddie.

“Incredibly selfless, she would always look to put other people before herself. She desired nothing more than for everyone around her to be happy and loving. She worked tirelessly on numerous charity campaigns, creating memories for many individuals and their families.

"It wasn’t uncommon for Johannah to hear through the media of an individual in need of assistance, and she would immediately make it her objective to get that person what they often desperately needed, and rarely without success.

"These are the things that made Johannah happy and content in life, and all of which for me made her simply the perfect wife and best friend to face each day with.

"I thoroughly loved walking through life with her, and though five years was far too short a time, during that time we had so many lifetimes worth of happiness, adventures, and memories.

“We would like to send our sincere thanks to Professor Steve Mackinnon and his team at University College London Hospital where Johannah was hospitalised since May. And during the last few weeks Professor John Snowden and his colleagues at Royal Hallamshire Hospital Sheffield.”

Our hearts go out to Louis and his family at this time.
