Lily Allen has blamed Girls Aloud star Cheryl Tweedy for sending her into a spiral of depression over her looks.
The 22-year-old singer posted a tearful confession on her Myspace page complaining she felt "fat and ugly" and saying she was considering plastic surgery.
Now Allen has revealed it was brought on by reading hurtful comments in which Tweedy branded her a "chick with a d***".
In her latest post, Allen said Tweedy's jibe - coupled with the constant comparisons to supermodel Kate Moss as they launched rival fashion ranges - which pushed her over the edge.
And she hit back with a furious rant at Tweedy.
She wrote: "Hi guys, I'm sorry if I worried anyone with the blog I wrote yesterday. I was feeling pretty sorry for myself. I've been reading all your comments and they have made me realise there is more to life than being thin! So thank you.
"I think I was just having a hard time last week after reading Cheryl Tweedy's comments branding me a 'chick with a d***'.
And in a blast at Tweedy, who is married to Chelsea star Ashley Cole, she wrote: "Cheryl, if you're reading this, I may not be as pretty as you but at least I write and SING my own songs without the aid of autotune. I must say taking your clothes off, doing sexy dancing and marrying a rich footballer must be very gratifying, your mother must be so proud."
Tweedy made her comments during an appearance on Gordon Ramsay's Channel 4 show 'The F Word.'
