Liam Payne on Celebrating His Son's First Christmas and Reuniting With Niall Horan (Exclusive)

The former bandmates are clearly still close.

Fate brought Niall Horan and Liam Payne in one direction on Friday night!

The former 1D bandmates reunited at KIIS-FM’s iHeartRadio Jingle Ball presented by Capital One at the Forum in Inglewood, California. 

Horan and Payne performed separately at the concert, but couldn't help but chat it up backstage. 

"You guys already saw Niall. What a great set he had," Payne told the crowd during his set, before posting a photo of their reunion on Instagram. 

"@niallhoran good to see you bro," he wrote, while Horan replied, "You too bud. Great few days. See you at home." 

Payne spoke to ET's Katie Krause on Friday, where he called reuniting with Horan "fantastic."

"I mean we played a bit of Playstation yesterday in my hotel room in San Jose," he shared. "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."

Payne also talked about his holiday plans, his first one since welcoming son Bear in March.

"Well, I have a little nephew that's just been born as well, who's younger than Bear -- little baby Ashton.," he said. "It's gonna be a very baby full house. I imagine the happiness and love around is gonna be amazing."

Though One Direction went on hiatus in early 2016, Payne and Horan have reunited several times this year. The singers were both at KIIS-FM's 2017 Wango Tango music festival in Los Angeles and at the ZPL Birthday Bash in Indianapolis. 

Zayn Malik, however, admitted this fall that he's lost touch with his One Direction bandmates. 

"Our relationships have definitely changed since we were in a band together, but I think that’s just life,” the 24-year-old singer told Billboard. “Everybody grows up; two of the guys have got kids now. But no, I don’t talk to any of them, really.”
