Why is Lilly Allen the face of Chanel?

She can't sing, she isn't stylish so why is Lilly Allen the face of Chanel? I believe someone who should be the face of Chanel should be sophisticated, elegant and glamourous! by the way she in none of these things...I don't get it i really don't. I think it it has just turned of one of the most successful designers ever to a joke of an advertisement!!! Harsh but fair....
