British pop star Kate Nash has said she would love to run her own ice cream business if her music career ends.

The Foundations singer revealed the alternative career plan during an interview with Time Out.

"I would open my own ice cream parlour in London," she said.

"I would put on little nights and serve up 'proper' knickerbocker glories with luminous green sauce while wearing a cute checked apron."

Nash also revealed that she tested boyfriend Ryan Jarman early on in their relationship by sending her mum to pick him up from the train station.

"If you fancy someone I think you should throw them in the deep end straight away," commented the singer.
