Though One Direction went on hiatus in early 2016, most of the band has remained on good terms -- with Horan and Payne reuniting several times over the last few months.
"We played a bit of Playstation yesterday in my hotel room in San Jose," Payne told ET in December of playing Jingle Ball concerts with Horan. "He came and hung out for a little bit, but it's just so nice to see him. I don't know, when you see someone you haven't seen for ages, you become the same person that you were with them. I don't know, it's very interesting."
