Is Zac Getting Older?

Zac Efron was sporting a half-stache tonight on the Teen Choice Awards red carpet and me thinks he's looking a tad bit ... old! And by old I mean, like 25. But still, doesn't that extra hair above his lip just add a couple years? Anyway, the HSM star picked up the awards for best comedy movie actor and for best mucis/dance actor in the third installment of the hit series. And here's what he had to say about his new surfboard ... Does he think he's Megan Fox, or what?!
