As Amy Winehouse knows, you haven't got a drug problem until a national newspaper films you tootling on a crack pipe.

But now that the whole wide world has seen her huffing crack like it was going out of fashion, it looks as if Amy Winehouse has reconsidered a spell at that rehab that they kept trying to make her go to.

Still, though, maybe Amy Winehouse will benefit from this - it's only through great suffering that great art emerges. Great art or embarrassing off-kilter wailing. We can never remember which one of those is right.
