Lily Allen has called Katy Perry "crass" in an explosive interview with Capital radio. "I happen to know for a fact that she was an American version of me. She was signed by my label in America as, 'We need to find something controversial and kooky like Lily Allen.' And then they found her," she ranted. "I think the lyrics and stuff are a bit crass. When I met her I was bit frosty with her because someone asked her to describe herself. She's like, 'Aha, I'm like a fatter version of Amy Winehouse and a skinner version of Lily Allen!'. It's like, you're not English and you don't write your own songs, shut up!"
