The 25-year-old star is currently pregnant with her first child and is preparing for life as a mum with a new house in the country.
Allen quit music earlier this year and recently set up a vintage clothing store with her sister Sarah Owen.
Speaking to the UK's S magazine, she said: 'I've had enough of Lily Allen. I want to be me now. Whatever situation I'm in, whether it's going to the supermarket, the pub or a club, or in the back of a cab, people think they know me.
'And the reality is they don't. Lily Allen is a character I have no control over. It has nothing to do with me except my face is the one that goes with it.'
