Celebrity Green Teens Inspire Action

Gen-Teen Greenies (GTG) are gifted, smart and going places -- in their hybrid rides. They eat locally sourced organic munchies, drink fair-trade lattes, tune in to activist songsters like Jack Johnson and Ben Harper, and strive to waste not, want not.

So it's no surprise that so many GTGs turned out en force at Disney Studio's Burbank lot for the "Chevy Rocks the Future" event, where GM displayed some tight clean vehicles.

Bulbs went ballistic for 12-year-old "Little Miss Sunshine" Abigail Breslin, who definitely (maybe) did some surprisingly professional green-carpet posing. Kyle ("Cory in the House") and bro Chris ("Zoey 101") Massey jokingly sparred with TheGreenCarpet: Hollywood (TGC:H) over which of them is greenest.

Another Disney Channel star, Shanica Knowles (Amber on "Hannah Montana") wasn't quite as P.C., whispering her eco-confession to TGC:H: "See this gum I'm chewing? Sometimes I just throw it out. On the ground." The 18-year-old laughed. "Yes, it's bad. I'm bad." Um, like, yeah. Totally.

And, though 14-year-old sisters Milly and Becky Rosso (twins who play opposite Dylan and Cole Sprouse on "The Suite Life of Zack & Cody") can't drive yet, they told TGC:H that hybrids would be their kind of rides.

Nearby, former Miss USA and "Crowned" host Shanna Moakler demonstrated that she hasn't lost her pageant powers of addressing the tough topics. Travis Barker's on-again/off-again babe pontificated on how education is the most critical thing about being green. "You need to go online, learn about global warming, understand the impact," she told TGC:H. And, of course, practice recycling and do "small things, like turn off the water when you're not using it."

Erstwhile "90210" teen Luke Perry said his kids keep him green. "They're the ones bugging me to recycle and do the right thing," admitted the former sideburned heartthrob, who posed with former TV soul mate Jennie Garth in front of one of Chevy's $1 million no-fuel cars.

And, while Kate Beckinsale pouted behind oversized sunglasses, Joely Fisher, Jim Belushi and Billy Baldwin (with wife Chynna Phillips) served up big smiles as they ushered their drooling offspring into the eco-interactive tents to watch Kevin, Nick and Joe Jonas perform their hits "Kids of the Future" and "SOS." (Singer Jordan Pruitt was their opening act.)

The too-hot Jonas Brothers, who own a Chevy Tahoe 2 Model Hybrid SUV (and much-ballyhooed purity rings), make our list of Gen-Teen Greenies, but what are other young celebs doing for the cause?

Hilary Duff champions USA Harvest (as does Green Day and Scarlett Johansson), donated big bucks to Katrina victims, helps out at homeless shelters, and is a huge supporter of eco-fashion -- she wears mostly vintage.

Alicia Keys is a giver: She's ambassador for Keep a Child Alive (an African AIDS organization whose supporters include Avril Lavigne and Ashley Simpson), sang at Live Earth and gets behind a multitude of other causes.

UNICEF's Goodwill Ambassador Shakira not only shook her heart of gold at Live Earth, but the Colombia native also founded Pies Descalzos (Barefoot Foundation) and donated 10,000 pairs of sneakers to her impoverished hometown of Barranquilla.

Vegetarian singer Joss Stone has some nice activist creds for playing at Live Earth, fighting world hunger and being a PETA spokesperson.

Fifteen-year-old Q'orianka Kilcher campaigned for Amnesty International on the subjects of the rights of women and indigenous people and petroleum-industry contamination of the Amazon River Basin. She's also the teen celebrity spokesperson for Thursday's Child, an international charity for at-risk children.

In November 2007, real-life hero and whale and dolphin champion Hayden Panettiere was awarded the Compassion in Action Award from the animal rights group PETA.

Singer Rihanna rocked Live Earth from Tokyo, Japan, and offered up her time to judge the Alliance for Climate Protection and Current TV's green video contest. She also started her own charity called Believe.

Besides her recent split from hubby Corey Hart, animal-loving activist Pink also made headlines for protesting the use of horse-drawn carriages in the Big Apple. This rocker makes loud moves for her various causes -- including Greenpeace and PETA.

Orlando Bloom is eco's swashbuckling poster boy -- he donates time to Global Cool and Global Green, among others.

Chelsea Staub / Ben Tilden

Keira Knightley's a big supporter of Oxfam International (as are Beyoncé and Justin Timberlake), UNICEF and Charity Projects Entertainment Fund (the org featured on last season's "American Idol").

The "Harry Potter" clan is also displaying their eco-friendly sides. Emma Watson donates time to The Wild Trout Trust, while Daniel Radcliffe gives to the Charity Projects Entertainment Fund, and promised to buy a hybrid when he got his license. (Did he?) But we're not seeing Rupert Grint working any green magic.

NEED TO GET THEIR GREEN ON:

Miley Cyrus pledges to be a good role model for young'uns -- so making her colossal concerts enviro-friendly would do the trick.

Can Zac Efron do a bit more than show up to award shows in an eco-limo and wear an OmniPeace T-shirt? Just asking.
