Welsh singer Duffy is back with a new album Endlessly and single Well Well Well, after her first album launched her into the limelight in 2008.
She refused to talk of how her music has changed since the first album Rockferry, saying "I would feel as though I was too self aware of my change as a person".
But she did reveal how she keeps herself from being sensitive about reviews, saying the only critic she takes notice of is herself.
