Lilly Allen is stirring up controversy yet again as she publicly dissed “I Kissed a Girl” singer Katy Perry during a recent radio interview.

Speaking with UK radio station Capital FM, the supposedly sober songstress had the following to say about Perry:

"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… 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!"

A little harsh Lily, don’t you think. And by the way, has anyone ever mentioned to you that you’re the UKs fatter, less successful version of America’s Britney Spears?

Who needs to shut up now?

Jealousy is not a good color on you, Lily – not at all.

So we need to ask: Katy Perry vs. Lily Allen – Who’s side are you on?
