PUT YOUR LUNCH DOWN. YOU'LL NEED YOUR MOUTH FULLY OPEN FOR THIS.
Sienna Miller, aka her of the world-famous blonde locks, has gone and dip-dyed her hair. Pink. You could go so far as saying it's a sienna-red shade, only it's not. So we won't.
Ms Miller debuted her dip-dyed 'do (try saying that while you're eating) at Ibiza airport - following in the footsteps of, err, Pink - as she embarks on a little holiday with her new beau Tom Sturridge.
A new look at 38,000 feet? There's no stopping this style icon.
Or is there? Do you like Sienna's new hue? Do you prefer Kate Bosworth blue? And why oh why are all the stars dip-dying their locks this week? Does this mean we should all do a dip-dye too? To dip-dye or not to dip-dye?
SO MANY QUESTIONS PLEASE ANSWER SOME OF THEM, below...
