Welsh stoner comedy rap troupe Goldie Lookin' Chain have launched a vicious attack on Lily Allen, describing her as "thick as pig shit".

"Lily Allen is as thick as pig shit. She'll say anything to get in the news," MC P Xain told the, er, Daily Star.

"The worst thing is she has so little substance to what she says that people pick up on things like: 'Oh, I did cocaine'. Any time she says anything controversial it ends up on the front of the paper," he added.

Goldie Lookin' Chain were a satirical exercise who became famous in 2004 for such cerebral ditties as 'Your Mother's Got A Penis'.
