Lily Allen has described her former celebrity mates as a 'bunch of sterile f***ing Botoxed idiots' who dropped her from their circle when she became pregnant.
Lily, 28, who 'retired' four years ago to raise her two children, Ethel, two, and 11-month-old Marnie, told Esquire magazine: "I thought the people in that showbiz circle were my friends. But almost the second I got pregnant and I wasn't able to go out and party, they were suddenly quite nasty.
"There's a way that those people survive and it's not by being nice. The way they make themselves feel powerful is to ostracise other people."
She added: "I feel blessed to be able to recognise that, but at the same time it can still feel pretty s**t when you walk into a room full of people and you can feel the eyes looking at you and people laughing."
Describing her decision to take time out after she became a mum, Lily - who returned to the spotlight singing the bear-and-hare John Lewis Christmas ad - said: "I was at the end of my tether. I'd had enough of people constantly hacking at me. And I think once you're exhausted physically and mentally, it does get you down.
"I feel like when I was growing up and dreaming of being a pop star, it was the days of Britpop when things felt authentic and anarchic and people were taking drugs and having a lot of fun and having sex with each other.
"So excuse me if I found it a bit disappointing when I arrived and it was a bunch of sterile f***ing Botoxed idiots that stank of desperation."
