Louis Tomlinson is still grieving the loss of former One Direction bandmate Liam Payne. "It was really, really, impossibly difficult for me to deal with losing Liam," Tomlinson, 33, told Rolling Stone UK in an interview published on Tuesday, October 7. "Naively, I thought that because at this point, I'm relatively well versed in grief for my age, that it might soften the blow." Tomlinson was referring to the loss of his mother, Johannah Deakin, who died of leukemia at age 43 in 2016. Three years later, his younger sister Félicité Tomlinson died at age 18 following an accidental overdose.
