Zac Efron Nearly Bares Butt in Australia

If not for his undies, Zac Efron would have shared his bare butt with lots of folks in Sydney, Australia. Pulling a recent Justin Bieber move, Efron wore his pants so low he left practically nothing to the imagination.

According to a report from Celebuzz, even though Zac looked incredibly hot when spotted on the balcony of his Sydney hotel, he claims he doesn't consider himself to be a hearth throb. Do you think he is?

The star

of The Lorax and soon to be very sexy star of The Lucky One went a step further on his hotel balcony, too, and actually removed his pantsÂ—along with his shirtÂ—to soak up a bit of the warm Sydney sun.

Zac Efron's first really big claim to fame was his role in High School Musical and the fact that he met the other half of his long-term relationshipÂ—Vanessa HudgensÂ—while playing it. The Lucky One is likely to thrust Zac directly into the spotlight in a far more grown up role, and cast him into the sexy heart-throb categoryÂ—for those who don't already think he's there.

You can check out some photos of Zac baring his Calvin Klein boxer briefsÂ—but not his entirely bare buttÂ—by clicking here.

Do you categorize Zac Efron as a current heart-throb or someone who will soon be one?
