One Direction have been teasing fans with little previews of their new track, and now here's some more enticing information for fans!

Earlier in the week, they posted a line from the song: “Your hand fits in mind like it's made just for me....” and then added “But bear this in mind, it was meant to be.”

And now Ed Sheeran has revealed some more lyrics! Here's what Ed said about the song:

“It’s got one of my favorite lines that I’ve ever written in a song. Harry says, ‘I know you never like the sound of your voice on tape / And you never like to know how much you weigh / And you still have to squeeze into your jeans / But you’re perfect to me.’

Ed called the song “acoustic led”, “something different, “ and “an appreciation song.”

He also revealed who the song is about:

“I wrote that song with a girl called Fiona Bevan when I was 17 and we lost the song. I’ve kept in touch with Fiona, we’ve done gigs and stuff and about two months ago she sent me the tune and was like ‘Oh, do you remember this?’” he explained. “I was like ‘Yeah, I do remember that!’ And I was in the studio with the One Direction boys at the time that I was playing it and they were like, ‘We really like that.’”

We can't wait to hear what the song sounds like!
