So earlier today we posted this photo and asked: WHO is this?
Amazingly, the answer is (the formerly raven-haired) Crystal Renn!
We didn't even recognise the supermodel when we spotted the photographs of her, as she appeared last night, at the 9th Annual Spring Dinner Dance 'New Year's in April: A Fool's Fete', at the Mandarin Oriental Hotel in New York.
This fiercer look is quite a change of direction for the once plus-sized model.
So what do you think of Crystal's newly-peroxided locks...and matching brows? Answers below, please.
