Lily Allen has reignited her feud with pop rival Katy Perry after allegedly threatening to leak the I KISSED A GIRL singer's phone number online.
The Smile hitmaker was incensed when Perry described herself as "a fatter version of Amy Winehouse and a skinnier version of Lily Allen" last year (08).
Pop newcomer Perry has since apologised to Allen for the remark, claiming she "didn't mean anything by it".
But according to British tabloid reports, Allen is still fuming, and has taken to her social networking page on Facebook.com to air her disgust.
The Sun newspaper alleges Allen has joined two online groups called, 'I hate Katy Perry and her dumb-ass song I Kissed A Girl' and 'Katy Perry? Who in the hell does she think she is?'
And Allen is also reported to have posted a message on her site that reads: "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."
A spokesperson for Allen could not be reached for comment as WENN went to press.
