Blimey! Talk about a quick change! It's enough that Hollywood startlets seem to find a different outfit for every red carpet event during Cannes, but it seems they can dramatically change their hair length too! At least, Naomi Campbell can. Naomi broke out a stunning 1920s style bob at Saturday's premiere of You Will Meet a Tall Dark Stranger, sporting a full length Givenchy gown. Next up, she stepped out working long tresses for the premiere of Biutiful last night. It looks like she's been using extensions or a fabulous wig to switch her looks. Naomi is in Cannes for the festival with her ultra-glam Russian boyfriend Vladislav Veronin attending a slew of events. Which look do you prefer?
