Last month, Katy Perry started a war of words when she said, “Aha, I’m like a fatter version of Amy Winehouse and a skinner version of Lily Allen!”

“

Those words didn’t sit too well with Lily Allen, who came back with, “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… It’s like, you’re not English and you don’t write your own songs, shut up!”

Afterwards, Katy took the opportunity to apologize to Katy for the mixup, saying, “Yeah, I made a joke about that earlier this year. I was just kind of joking and trying to be funny. I didn’t mean anything by it. Comedians are not necessarily to be taken super seriously.”

It’s not funny anymore, because Lily Allen isn’t letting their feud go. She reportedly wrote on her Facebook that she has Katy’s phone number and may just put it on the internet.

Writing on her Facebook page, Lily said: “I have Katy Perry’s number, someone did me a favour. I’m just waiting for her to open her mouth one more time then it hits Facebook.”

An anonymous tipster sent this in. Fake? What do you think?

Lily also joined two groups on the networking site. One is called “I hate Katy Perry and her dumb-ass song I Kissed A Girl”. The other is “Katy Perry? Who in the hell does she think she is?”
