Amy WinehouseAmy WinehouseAmy Winehouse has torn strips off a fellow celeb.

But who's the lady who's got the sharp end of her tongue?

It's little ol' Charlotte Church.

Amy made a bit of a boozy appearance on the Charlotte Church Show last October.

And let's just say it was memorable stuff... for all the wrong reasons.

But she doesn't seem to give a tinker's toss.

She said: "Why should I? If something troubles me, I speak my mind.

"That's why they invite me.

"Church is an arrogant cow. And Bono isn't much better. He thinks he's God."

And there's how NOT to make friends and influence people, everybody.
