What happened to Orlando's hair?

Last night's Global Green pre-Oscar party guest list felt more like the Grammys: Maroon Five, James Blunt with Petra Nemcova and Russell Simmons. But Hollywood hunks Leonardo DiCaprio, (up for an Oscar on Sunday), Orlando Bloom and Olivier Martinez (otherwise known as the creep who ditched cancer survivor Kylie Minogue) created party heat at the Avalon Hollywood and Oscar-nominee "Volver" star Penelope Cruz added spice to the night. What's up with Orlando's bizarre unmade bed head? Be nice. We don't want him to start wearing that dorky porkpie hat again. Besides, the gel OD is better than that icky ponytail.
