Miranda Kerr: Nude in Rolling Stone Australia

She may not be in Gisele Bundchen or Marisa Miller territory in terms of riches or fame, but Miranda Kerr's latest modeling endeavor could change that.

The Aussie stunner, who may or may not be engaged to Orlando Bloom, bares it all on the cover of Rolling Stone Australia's upcoming Green Issue.

Now that's how to get people talking about green initiatives and climate change. Speaking of which, is it getting hot in here, or is it just this photo ...

Beautiful, chained and naked, Miranda Kerr pleads for environmental action.

Miranda Kerr's decision to pose in her birthday suit stems from a desire to raise awareness about the environment - most notably, the dangers faced by koalas.

"It's incredibly sad. There are only something like 100,000 koalas left in Australia," the 26-year-old says. "Something like 80 percent of the koalas' habitat has been destroyed since Europeans arrived in Australia."

Wow. Doesn't such devotion to a good cause make you want to give her a hug? If not, then these Miranda Kerr pictures will change that quickly.
