Louis Tomlinson reveals what caused his and Zayn Malik‘s fall out.

During a recent interview on The Dan Wootton Interview podcast on Friday (March 8), the 27-year-old singer revealed that his relationship with the 26-year-old “Pillowtalk” singer went south after Zayn didn’t show up to Louis‘ 2016 X Factor UK performance of “Just Hold On,” which was a tribute to his late mother Johannah Deakin – who had just died of Leukemia.

One Direction bandmates Harry Styles, Liam Payne, and Niall Horan all attended the performance to show their support, but Zayn did not show.

“Truthfully, [our relationship] never really got better,” Louis shared. “I had a couple of calls with him after I lost my mum and all the boys had agreed to come to that performance and he didn’t show so that really bugged me.”

“It was just seeing everyone there – Harry, Niall, and Liam — that was what I needed that night, that support,” Louis shared while adding he still hopes Zayn is doing “alright.”
