Hmmm. There's a new trend sweeping Hollywood and we're not entirely sure we're comfortable with it. Celebs are choosing to wear their hair half-up, half-down. Over the weekend we spotted the style on Natalie Portman at the AFI Film Festival screening of Black Swan; we'd already seen it on Camilla Belle at the 2010 Freedom Awards, and Lo Bosworth debuted the look at the MTV Video Music Awards in September. Now our initial hmmmm-ing at this look isn't to do with the girls looking bad. In fact they look rad. 'Specially Nat and Camilla. No offence, Lo. (None taken.) It's just that we wore the style in Year 4 when we were trying to attract Andrew James' attention, even though he was more interested in eating mud. It's a school girl's style. Or it was. And now we have to re-train our brains because it's cropping up left, right and centre on the red carpet. But we think we'll make like Nat and ease ourselves into the trend by twisting a coupla strands back. Non-committal? Us? Pfft. Never. You like? Will you wear it?
