Duffy has said she is not troubled by her recent chart flop with comeback single ‘Well Well Well’.

The single entered the UK Chart at a disappointing 41 - a step back from the singer’s previous number one hits.

'‘I'm not the sort of person who sends demos home to their mum asking if she likes it. I don't really search for approval from others,'' Duffy told The Sun.

On her decision to change producer for the album, she added: ‘‘I think without struggle there is no progress. Without experimenting there's no development. So I had to push myself. I wanted to make people dance. I wanted to make them move emotionally or physically."

Duffy’s new album ‘Endless’ is released today (November 29) and sees her work with The Roots and Albert Hammond Snr.
