Nicole Kidman nearly nude in pics for V Magazine

Nicole Kidman stripped down for the cover of V Magazine's travel issue, wearing a piece of black fabric that some might mistake for a skirt -- aside from the fact that her bare bum is hanging out.

Inside the magazine, she slips into something a little more comfortable -- with a little more coverage -- just some lace underwear and a red fur coat (you know, your typical hanging-around-the-house ensemble) and discusses peeing on Zac Efron -- or rather his character in "Paperboy" after he was stung by a jellyfish.

"The peeing thing, I didn't think that was weird, because I was in character," she tells the mag.

In the issue, which hits stands Aug. 30, she also dishes on her husband, Keith Urban, their two children, and an upcoming cameo in Lars von Trier's film "Nymphomaniac."
