"It was at a big party in Coco’s apartments in Paris. I was drunk and got lost in the building. I wandered into an attic room and Karl was there. I got really embarrassed and apologised, but he said, 'No, come in.' We had a chat – although I can’t remember what about, I was so drunk. I do remember asking him about some shoes he’d designed that had a green ring in the heel [from the Chanel a/w 2009 collection]. I asked how they worked. He drew a diagram explaining the physics of making the shoe. I’ve still got the drawing. A week later I was asked to do the campaign." - Lily Allen in the August issue of Elle UK.
