7 Sexiest Green Celebs

Dominique Charriau

Brad Pitt

This corn-fed, Oklahoma-born, man-boy from Missouri is more than rugged good looks and a hard body (People named him Sexiest Man Alive...twice) Thanks to the stalkerazzi, we're privy to this benevolent gentleman's every good deed. Following a laundry list, Pitt led a massive green building project in Katrina-devastated New Orleans. Pitting (ahem, excuse me) a team of world-renowned green architects for projects, Brad is determined to start an unprecedented green building trend.

Hayden Panettiere

Though best known for her role on NBC's Heroes, Hayden Panettiere is raising praise and eyebrows as a young environmental and animal-rights advocate. In October '07, Panettiere interfered with Japan's annual dolphin hunt and has since served as a spokeswoman for PETA and other animal-rights organizations. Check out Hayden on earthfirst.com's Top 25 Hottest Girls In Green.

Jason Kempin

Adrian Grenier

Unlike the character he plays on TV, Entourage star Adrian Grenier cares about the environment — no, he doesn't drive a bright yellow Hummer in "real life"! Grenier prefers driving a Prius, living in a fully "green" house (solar roof, reclaimed floors, recycled blue-jean insulation, blah, blah, blah), and offsetting. In 2007, Grenier drew massive attention to Charity Water, a nonprofit initiative that sets up drinking water and sanitation infrastructures in the world's most impoverished communities. Word in the 'hood says Grenier is "fully committed to educating any lady who dares walk into his green life." According to environmental gossip site ecorazzi.com, Grenier said, "If a woman isn't environmentally conscious, she will be after going out with me." Too bad, I'm already environmentally conscious...

Mark Von Holden

Sheryl Crow

Sheryl Crow is a green queen. In addition to advocating "one square per restroom visit," the singer raised mainstream green awareness by touring the country in a biodiesel-powered bus. With Laurie David at her side, Crow threw the smackdown on Karl Rove. After the former senior White House adviser scoffed at global warming evidence, Sheryl got feisty. "You work for us," the singer said, famously.

Dimitrios Kambouris

Sienna Miller

It's hard to keep track of this British beauty's breakups, make-ups...and then again breakups; yet, Sienna's eco-record is as clear as the see-through bra she sports in Hippie Hippie Shake. An ambassador for the UK-based climate-change campaign Global Cool, Miller recently launched the carbon-neutral clothing line Twenty8Twelve. In October 2007, Sienna received an EMA Futures Award — an honor given to those who use their talent and celebrity to draw attention to the problem of global warming. Yay! Now we can raise our beers to eco-activism and sexy starlets...it's Miller time!

Steve Granitz

Alicia Silverstone

Named 2004's Sexiest Female Vegetarian, Alicia Silverstone has appeared in a series of (yes, nude) ads for PETA. The Clueless star has also set up a pet sanctuary in Los Angeles, a city she claims is hard to live in without driving. But not to worry! Alicia drives a hybird. For all this and more, check out why the Huffington Post Green also calls Alicia out for being one of Hollywood's "Hot Green Things."

Jean Baptiste Lacroix

Al Gore

I had to! This greenie may lack chiseled abs and cheekbones. Nonetheless, Al Gore has consistently turned us on with unbridled activism and inspirational gusto. You go, Gore!
