Lily Allen has revealed that she dreams of opening a whole chain of vintage clothing stores in the future.

The pregnant singer launches her London store Lucy in Diguise tomorrow (September 16), and is taking a hiatus from music to focus on running the Covent Garden-based shop with her half-sister Sarah Owen.

"We'd love to roll out to other locations but at the moment we're taking each day as it comes," Lily excitedly told Stylist magazine.

Allen is also teaming up with Donna Ida jeans to raise cash for charity. She explained, "They approached us about doing a denim drive for the Jeans for Genes campaign and we jumped at the chance. People can drop off their old jeans at our shop and we'll give them vouchers for new Donna Ida jeans with 50 per cent of the proceeds going to charity."
