Pink wrote a song about an argument over butter.

The singer explained how 'Just Give Me a Reason' on her new album, 'The Truth About Love', is inspired by the small signals a person can give when a relationship is breaking down.

She told music streaming service Spotify: ''Sometimes [one partner] can be like, 'The way you passed me the butter this morning, I kinda feel like we're going to be over in a month and we need to talk' and he's like, 'I just passed you the f***ing butter, what are you talking about?' and that's how I felt the song should go, 'We're growing apart, you don't spoon any more, like it's all over'.''

Pink - who is happily married to motorcyclist Carey Hart - wrote the track with Nate Ruess from the band Fun. and decided it should be a duet, but had to trick him into singing it.

She added: ''I was like, 'no, this is a story, this is a conversation this song' - it needs the other perspective whether it's a guy and a girl, or two girls or two guys.

''I came in and tried to convince him that this was how the conversation was going to go and it was interesting you know, he was like 'I'll just do the demo cos I don't know about duets' and I totally tricked him into doing it, and I am so glad I was able to.

''I think now he's very happy that he did it, I think it's a beautiful song and I'm really, really proud of it.''
