British singer-songwriter Ed Sheeran has revealed that he recently wrote an angry song about someone he knows and doesn't think the public will be able to accurately guess who it is about.

Speaking to MTV News about the track, he explained that there's bad language in the song for a reason because he really wanted to get his point across: "I tried other words, I tried 'mess', I tried 'funk', lots of other things, but none of them worked. I think if you're going to swear on a track, make it worth it."

"There's no point in swearing for just the sake of it... but, if taking away a certain cuss word lightens the load of the song, I don't agree with that. So I've kept certain words in just because it makes the song what it is. But, I'm definitely giving radio an edit they can play, because I'd be mental not to."

The 'Lego House' star added that he doesn't want to bring the person in question any embarrassment so won't name them, but believes they might know it's personal when they hear it:

"Naming and shaming, I'm not in the business of that. I can tell you one thing, it's not about who people think it's about; people won't be able to guess. But the person who it's about will probably be aware. But when you're a songwriter, and if someone's dating you and they know you're a songwriter... if good things happen, good songs get written. If bad things happen? Bad songs get written."
