Okay, now we know Zac Efron is tall and thin. We also think he's somehow gotten hotter than Chace Crawford - I know, right?
But what we didn't know 'till now is that he's actually gotten buff. Just look at those arms!
Guess all those trips to the gym have been paying off! Check out more Zac Efron hottness in the gallery below...
Keep up the good work, Zac!
