Florence Welch feels guilty about her lyrics.

The Florence and the Machine star - whose track 'Dog Days Are Over' consists of phrases chosen at random from an art installation - says she sometimes wishes there was more of a story to the lyrics she writes.

She said: "'Dog Days Are Over' means nothing. Sometimes I feel guilty about how flippantly I choose lyrics. If I like a phrase I just put it in. And then it means something to people."

Florence also revealed she had a panic attack when she learned she was going to be honoured with the Critic's Choice Award at this year's BRIT Awards.

She explained: "I'd done nothing and I was getting an award for it. Even on the day of the awards the only way I felt I could stand up there and receive it was to thank the people who had helped get my music out and put it on the radio."
