Styles was discussing the possibility of 1D reuniting during his appearance as a guest on the final episode of The Late Late Show to be hosted by James Corden.
The pair discussed the possibilty during the infamous Spill Your Guts or Eat Your Guts segment of the show, and while a reunion may not be in the works at the moment, Styles refused to rule it out in the future.
Corden asked, "Yes or no, will there be a One Direction reunion? Will it ever happen?".
To which Styles replied, "I fear that it's not a yes or no question. I think I would never say never to that. If there was a time when we wanted to do it, I don't see why we wouldn't".
One Direction which consisted of band members, Liam Payne, Niall Horan, Zayn Malik, Louis Tomlinson, alongside Styles, have been on haitus since their break up in 2016, with Zayn Malik having left the group a year earlier.
Rumours had initially spread that One Direction were to reunite for James Corden's final episode as host of the US chat show. However, those rumours were quashed via an official statement.
"Nobody loves the boys more than us, but this [news] isn't true", they said. "What is true is we've got an absolutely brilliant 2 hour finale planned to celebrate 8 years of The Late Late Show at 10pm on April 27th".
