Hilary DuffHilary DuffOMG.

Someone's taken the term "bed hair" a bit too literally.

What on earth's happened to Hilary Duff in this pic?

The normally preened 'n' sleek singer looks like she's been dragged through a hedge backwards.

There's nothing wrong with using a hairbrush now again.

Not to mention some slap, even if you're after the "natural" look.

This is Hollywood we're talking here - the gal probably has her stylist on speed dial.

We suggest she uses it...

But in the meantime enjoy it while you can - see Hilary and other stars looking rough right here.
