Sleek, long and blonde are the usual adjectives we'd use to describe Rosie Huntington-Whiteley's enviable tresses - but it looks like we'll have to take a vocabulary rain check.
Rosie HW's debuted an exciting new 'do for the cover of Numéro Tokyo magazine's September issue.
She's ditched her famous golden locks (well, almost) in favour of new zingy green highlights. Colour chameleon Jessie J would approve!
Looking all kinds of punked up, posey Rosie wears her Met Ball mesh Gucci dress from back in May. Recycling her wardrobe and colour-swapping her locks, is the model turning a new leaf?
However subtle the change, the paper-thin streaks have transformed the model's pretty polished locks and given her a skater girl edge.
If we're to hazard a guess at the method behind her madness, we'd say the lime-lights are purely for her cover shoot - so rest assured her root to tip blonde locks will return!
