But now it's just flat and brown; lacking any personality. And speaking of lacking personality, could Zac maybe smile just once? He's so over this event! The Hairspray star hosted Nickelodeon's Australian Kids' Choice Awards in Sydney the other day... but it doesn't look like he was too excited to be there. You know he's missing the tanning salon like crazy!
