The 24-year-old singer -- who appeared on The X Factor to perform his emotional song "Just Hold On,” which he dedicated to his mom -- shared similar sentiments on Twitter before the show, writing, "All the support has been incredible! Let's do this together tonight."
Tomlinson's mother, Johannah Deakin, died on Dec. 7 after a battle with leukemia. She was 43.
"Johannah was first and foremost a truly amazing mother to seven children -- Louis, Lottie, Félicité, and two sets of twins, Phoebe and Daisy and Ernest and Doris -- whose individual talents and success are testament to the principles and beliefs she instilled in them," Deakin's husband said in a statement to ET.
