The pair had remained friendly since One Direction’s 2016 split, with Payne explaining to fans on Snapchat earlier this month that he was visiting Horan for a catch-up.
He said: “It’s been a while since me and Niall have spoken, we’ve got a lot to talk about.
“No bad vibes or anything like that, but we need to talk,” he added.
Payne attended Horan’s concert last week, again posting social media videos of himself and girlfriend Kate Cassidy singing and dancing to the performance.
Horan finished his world tour on 9 October in Bogota, Colombia, and reportedly then returned to his home in London.
He was the final member of One Direction to post an individual statement on the passing of 31-year-old Payne.
The band, which got together in 2010 on The X Factor, posted a joint statement on Thursday, in which they said they needed time “to grieve and process the loss of our brother”.
