Lily Allen is reportedly being courted by Chanel because Karl Lagerfeld - who has previously shunned the style of young celebrities - believes Lily’s mix of street-style and couture will be a key look next year.

A source told the Sun that Lily was invited to spend an afternoon with Karl in Paris last month to discuss the projects and came away with some new designer dresses to add to her collection.

The source added: “Lily burst on to the scene as the Queen Of Chav with her trainers and huge gold earrings so it’s hilarious she has been asked to work with Chanel, one of the most famous fashion houses in the world. But, like any girl, she loves high fashion.”

“Nothing is set in stone but Karl believes she has come up with a look that will define 2007. It’s all about wearing really classy clothes in a different context.”

“He is keen to dress her and work with her.”
