It is no secret that here at StyleList we love Kate Bosworth's fresh face, casual tresses and impeccable style. Her most recent look, however, has us questioning her sanity. Bosworth left a Coldplay concert last night with green locks. We are hoping that her new do is merely the product of spending too much time swimming in chlorine or, at the very least, a temporary phase. What do you think of her dip dyed 'do?

And if you think Bosworth's look is extreme, remember this blonde babe's rainbow locks?
