While we're used to seeing Damon clean cut, and even sometimes buzzed cut, he seems to pull of the ponytail quite well! Damon seems to be digging the new 'do too, given the high spirits he was in at the event. Maybe he can suggest this look as the perfect post-breakup hairstyle for his best friend, Ben Affleck?

It's still unclear if the Good Will Hunting star grew out his hair for a role, or if he just wants to fit in with the surfers this summer.
