It’s been reported the 21-year-old Smile singer carried on ranting about the pretty 17-year-old when she was off air.

According to the Daily Star, brunette Lily said she wanted to "kick her over and then kick her even harder when she was down".

It isn’t the first time Lily has had a go at her fellow celebs.

She recently slated pop diva Madonna, claiming the Hung Up singer was "overrated", and also - less controversially - had a dig at pampered Paris Hilton, calling her "untalented".

Lily slams the press - Sept 27 2006
Feisty songstress Lily Allen says she can’t be "bothered" to read stories about herself in the press.

The outspoken 21-year-old, who launches her latest attack on the charts this week with LDN, has landed herself in hot water on numerous occasions, taking swipes at Victoria Beckham, Kylie and Bob Geldof.

Speaking at the launch of 3FrontRoom, Keith Allen’s offspring says: "I can’t be bothered with it. I don’t do this for the press. I do it for the music.

"If I did it for the press I would’ve got a record deal from my dad four years ago and I wouldn’t have written any of my own songs.

"I would be prancing around taking my clothes off and singing cover versions which I don’t do. And going to loads of film premieres which I don’t do.

"It doesn’t interest me. I don’t care what people’s views are."

The singer recently provided backing vocals on the Basement Jaxx track Lights Go Down which appears on their fourth studio album Crazy Itch Radio, as well as on Robbie Williams’ latest album, Rudebox.

So what next? She says: "I’d like to work with Burt Bacharach. I think we could something really cool together. I suddenly had a revelation yesterday."

"I’ve been banned from America. That’s nice. Oh well, that means I can’t go back there. Good," the Daily Mirror quoted her as saying.

Speaking with an American accent, she added: "I’m going to dedicate this to the US. Obviously I’m really sad I can’t do my US tour. The shame is on you, the US Immigration Service."

Her best pal Miquita Oliver said: "Lily’s not bothered at all. She just wants to relax and chill out with her boyfriend and her mates.

"She’s not in the slightest bit upset, in fact it’s quite the opposite."
