‘I want to look really natural,’ she said. ‘I want people to like me for who I am rather than for how glamorous I am. It is what is inside that counts. My looks aren’t important to me.

'I feel like people should like my music whether I’m covered in a big brown paper bag or am wearing a skimpy outfit.’

She added: ‘I’m pleased people have been introduced to me while I’m a voluptuous, wholesome, curvy girl.
