The singer-songwriter has made appearances in the films The Imaginarium of Doctor Parnassus and St. Trinians in the past, and said that she would take it more seriously if her music career subsided.
"I'd moonlight as an actress, in Christina Ricci's roles if I wasn't a musician," she told Bang Showbiz. "I'd like to be an actress. That would be my plan B.
"I'd want to be cast in the sort of roles that Christina Ricci gets - quirky, avant garde and a little bit disjointed.
''I really loved her in Buffalo '66 and Monster. I'd probably have to look into theatre school first, though.''
She added: "When I was a child, I used to eat my dinner on the pavement outside our house in London.
''We didn't have a garden and there wasn't a lot of green space so my mum would put out a little table and tablecloth out on the pavement and pretend it was a restaurant. A little imagination goes a long way."
