Lily Allen Threatens Katy Perry

Love this feud between Lily Allen and Katy Perry. And I love Facebook. LOVE Facebook fighting. Do it, Lily!

Lily Allen has reignited her feud with fellow pop diva Katy Perry - by threatening to post her telephone number on Facebook.

The musical duo have been at loggerheads since Perry criticized Allen's weight.

And now Lily - who has since called the I Kissed a Girl hitmaker "crass" - says she'll publish Katy's details online if she says anything more about her.

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."

Lily also joined two groups on the social 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?"
