In the song, written by Sheeran when he was just 17, each member speaks to their respective girl, telling her exactly why he likes her "just the way you are". Nawww!
"The great thing about it is I wrote that song with a girl called Fiona Bevan when I was 17 and we lost the song," Sheeran told Capital FM.
"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?'
"I was like, 'Yeah, I do remember that', and I was in the studio with the One Direction boys at the time and I was playing it and they were like, 'We really like that'.
Of the line; "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", sung by Harry Styles, Sheeran says "It's got one of my favourite lines that I've ever written in a song."
Posted on YouTube yesterday, the unofficial video, featuring the poignant lyrics that Ed is so proud of, has already notched up nearly 2 million views!
Sheeran's quaint storytelling nature and effortless intimacy is all over this track, providing a mature departure from the pop-centric 1D chart toppers we've come to know and love. Is this new sense of emotional depth indicative of what we'll see on their new album, or is it just a one off Sheeran-inspired fluke? I guess we'll find out on November 12 when Take Me Home is released.
