We all know that Ed Sheeran and Taylor Swift are BFFs but even the closest of friends won't always see eye to eye with one another!

In an interview with MTV UK, Sheeran revealed that while he and Swift were writing the song 'Everything Has Changed,' the two singer-songwriters had a disagreement over one chord in the song.

“She has a little Taylor guitar, she got it out and she’s like, ‘I had this idea for this song,’" Sheeran recalled. "And she pretty much had the verse, bridge and chorus done, but we argued about that one chord — ‘I just want to know you, better know you’ — she didn’t like that, and I kind of forced it upon her.”

Uh oh! Luckily, the situation didn't become too awkward and the two moved on, although apparently without Taylor using her "I have a Grammy" card.

“It was quite a funny situation. It’s like [her room is] surrounded by Grammys; she has like seven or eight and like Billboard Awards and Songwriting Guild,” he said, “And I’m like, ‘this chord,’ and she’s like [pointing to her awards].”

It's a good thing they were finally able to finish the song since it ended up becoming a hit for Swift last year, hitting No. 32 on the Billboard Hot 100.
