Louis Tomlinson's relationship with Zayn Malik never recovered after he didn't attend Louis' tribute performance to his late mother.
The 27-year-old singer has insisted he hopes Zayn is "alright", but confessed that their friendship "never really got better" after Zayn didn't attend his 'X Factor' performance in December 2016, following the death of his mother Johannah Deakin.
He told 'The Dan Wootton Interview' podcast: "Truthfully it never really got better to be honest.
"I had a couple of calls with him after I lost me mum and, you know, all the boys had agreed to come to that performance and he didn't show and that really bugged me."
Louis admitted he appreciated the show of support from the other members of One Direction, Harry Styles, Niall Horan and Liam Payne.
