Whose bad roots?Whose bad roots?Call us demanding...

But we expect top models to be groomed to perfection.

We assume their nails aren't nibbled, their legs are waxed at all times, their slap is neat and in place and their hair is as if they've just stepped out of a salon.

Perhaps it's just a sign of how mega successful she is that she no longer has to worry about such mundane probs as two-tone hair.

She must just rock up to modelling jobs and someone else takes it on.
