"All the support has been incredible!" he wrote. "Let's do this together tonight."
The 24-year-old singer was referring to his pre-scheduled performance on U.K.'s The X Factor this weekend. According to a statement given to ET from Tomlinson's family, it will be a tribute to his mother, whose wish was for him to continue.
ET previously reported that Deakin died on Wednesday, Dec. 7, after being diagnosed with an aggressive form of leukemia earlier this year. She was 43. In addition to Tomlinson, she's survived by six other children, as well as her husband, Dan Deakin, and grandson (Tomlinson's only son with ex Briana Jungwirth), Freddie.
Although she's no longer dating Tomlinson, Jungwirth penned a sweet message about his mom via Instagram on Friday.
"My heart aches. Every time I look at Freddie I see you in him, Jay," she wrote. "I will always remember the times we shared and talks we had. I looked up to you and sadly only knowing you for a short time, I aspired to be just you in a mother to Freddie."
"I promise to share with him all of what I know of you, including all of your beautiful attributes," she continued. "We both loved you very much. You'll always stay close forever in our hearts."
Tomlinson's bandmate Niall Horan echoed Jungwirth's sentiments, writing, "Very sad news. Louis, I love you mate and I'm / all of us are here for you all the way."
"Your mum was an incredible person," he added. "Thinking of you and your family. Love from my family to yours."
