Shirtless Zac Efron Puts Our Heads in the (Charlie St.) Clouds

Even half-dressed, the actor is a safe tween dream

Oh, Zac Efron. So safe, so dreamy. Not even a jaunt to a strip club can make you seem dirty.

So when the wannabe stud whips off his shirt for an underwater sequence in his new flick Charlie St. Cloud, we just squee like a tween then trade Silly Bandz with our besties.

Hit the clip to swoon yourself, but we warned: It contains a plot point spoiler. A fair trade for a glimpse at Zac's six-pack, no?
