The British model has revealed her natural side in a new photoshoot with world-renowned photographer Rankin to mark WWF's global Earth Hour event on March 27.
People across the world will be turning off their lights for one hour, to take a stand for the future of the planet, reported Contactmusic.
"If we enjoy our planet then I believe we need to take care of it. I hope that people across the UK and the world will take a moment this Earth Hour to appreciate both the beauty and the fragility of the natural world that we rely on so much," Lowe said.
A host of celebrities are supporting this year's Earth Hour, including actress Jessica Alba and pop band McFly. Over 7,000 cities in 152 countries are expected to switch off as well as major landmarks like the Empire State building, the Eiffel Tower and the Great Wall of China.
