Niall also stayed for a chat on the sofa where he revealed that the 1D hiatus isn't expected to last forever and that a reunion could be sooner than we all think.

"For now we are doing our own thing," he told Graham. "We can't put a date on it but it won't be in 50 years. It's in the foreseeable future. 

"We've talked about it, but for now we'll just play it by ear and see what happens."

Also chatting about the double meaning of the new song, Niall explained that it really isn't about a secret love interest at all.

"It's not really about anyone in particular. When I'm writing songs, I write the concepts and then just write the scenario and then write the song around it," he says. "I guess with the 'town' part of it, there's a line in the song, 'Everything comes back to you,' and I still go home all the time, and no matter how far you traveled you still get to go home and be yourself. 

"And then it's obviously got that female aspect, too ... I got loads of texts from people from school saying, 'Everyone wants to know who it's about.' It's not about anyone. So, I cleared that up on national television."

Amy Adams and One Direction had met before on Saturday Night Live in 2014.
