Show's over! Zac Efron blocks Aussie paparazzi from snapping more nude shots

Zac Efron has built his very own "towel barricade" against prying photographers after a shot of his naked bum made it to the internet the other day.

The Hollywood heartthrob is staying in a swanky hotel on Sydney's harbour while he's Down Under to promote his new movie The Lucky One, and the views must be so stunning from his suite that he didn't even think to draw the blinds before getting naked at the weekend … and inadvertently giving the paparazzi a clear view of his bare butt.

The peepshow continued the following day when he was caught out on the balcony having a rummage with his hand down his pants.

Take note, lads: You never know who's watching.

But the paparazzi party is over now. Apparently Zac's had enough of our nosy Aussie photographers and he's fighting back — with 100% Egyptian cotton.

First there was the Berlin Wall, now, there's Zac's Manchester Wall.

Take that, paps!

Heads up, room service: He's going to need more towels!
