Lily Allen was shocked to be chosen to front a campaign for luxury French fashion house Chanel - because she was drunk when she met company boss Karl Lagerfeld.

The star was handpicked by Lagerfeld to front a campaign for the haute couture company's handbag line last year after the notoriously frosty designer admitted he found the Smile hitmaker "fun".

But Allen is still puzzled over how she managed to impress Lagerfeld, because she had been boozing and can't recall what the pair talked about during their business chat.

She tells Britain's Elle magazine, "It was a big party in Paris. I was drunk and got lost in the building. I wandered into an attic room and Karl was there. We had a chat - although I can't remember what about.

"I do remember asking about some shoes he'd designed that had a green ring in the heel. 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."
