Pop star Lily Allen has shocked fans by branding herself “fat and ugly” - and “s**tter” than fellow British singer Amy Winehouse.

The Smile star, who last week criticized the editors of fashion magazines for perpetuating the ’size zero culture’, made an impassioned turnaround on her MySpace page on Saturday.

She wrote, “Fat, ugly and s**tter than (Amy) Winehouse - that is all I am.

I’m on my own in America again.

“I used to pride myself on being strong-minded and not being some stupid girl obsessed with the way I look. I felt like it didn’t matter if I was a bit chubby ‘cos I’m not a model, I’m a singer.

“I’m afraid I am not strong and have fallen victim to the evil machine. I write to you in a sea of tears from my hotel bed in Seattle. I have spent the past hour researching gastric bypass surgery and laser liposuction.”

Speaking at the launch of her clothing range Lily Loves for British fashion chain New Look last Tuesday, she said, “Fashion editors can f**k off

Lots of them are responsible for the skinny issue. If fashion editors put bigger models in their magazines, then maybe girls wouldn’t be sticking their fingers down their throats so much.

“It makes me so angry, they should think more about what they’re doing to the younger generation.”

It would seem Maroon 5’s Adam Levine agees with her view after he labelled her a ‘A S**t Spewer’ Maroon Five frontman Adam Levine has branded British pop star Lily Allen a “s**t spewer” following her negative remarks about the US.

Earlier this year, Allen called U.S. President George Bush “an a**ehole and a c**t”, and referred to Americans as “backward” - and the Californian singer isn’t impressed with the young lady’s candid international commentary.

He says, “S**t constantly spews out of her (Allen’s) mouth. It’s not attractive seeing someone spew s**t out of their mouths.

“She’s bigger in the UK but her words still have some effect. Her talking s**t seems to be embraced.”
