Celebrity Eco-Couples: Green Ties That Bind?

Cameron working the Green Carpet at the Shrek Premiere and David speaking at Live Earth

The recent rumors that hottie eco-bachelor David de Rothschild has hooked up with longtime green girl Cameron Diaz got us wondering whether the enviro-minded make better bedfellows.

It would seem that isn’t the case with Larry David and his eco-activist wife Laurie. When they recently split after 14 years of marriage, Larry deadpanned, "I went home and turned on ALL the lights." And, it wasn't just the lights that rubbed him the wrong way. The "Seinfeld" creator has been known to complain about the less-than-plush recycled-content toilet paper he was forced to use while on Laurie's watch. He was even vocal about its scratch-factor on "Oprah," when the TV queen visited their home for a segment on what we can all do to make a difference.

Still, it was likely Laurie's pillow talk that drove Larry to pilot a Toyota Prius on his hit HBO show "Curb Your Enthusiasm." And don’t worry, Larry's TV wife, Cheryl (played by actress Cheryl Hines), will continue to play an activist on the show, despite whisperings that art may imitate life and see TV Larry and Cheryl split. Stay tuned.

Ed Begley, Jr and Rachelle Carson

And, it's gotta be organic love keeping überactivist Ed Begley, Jr. and his actress/producer wife Rachelle Carson together. Only the truly enamored would put up with having their showers timed! You can watch them butt heads on HGTV's "Living with Ed" (Season 2 premieres August 27).

But there are green ties that do bind. Pierce Brosnan first met his former journalist wife Keely Shaye Smith in 1994 when she was reporting on an environmental campaign. "She asked me for a few eco tips," Brosnan told an interviewer. Today, the former 007 and his real-life Bond babe are an environmental golden couple: They actively support numerous causes, eat and grow organic foods, and live in an eco-friendly house replete with radiant floor heating and solar vents.

Bono and wife Alison Hewson

Across the pond, Bono's commitment to Africa and ending world poverty and AIDS isn't the only activism going on at the Hewson household. Wife Alison started a hugely popular eco-fashion label called Edun (Nude backward), which will be strutted upon the catwalk during next month's Los Angeles Fashion Week.

So, we guess there's no guarantee that a green coupling will yield "happily ever after," but being joined at the green hips is something we can get, um, behind.

The "G" list

This week's celeb-types earning green thumbs up...

Al Gore's daughter Sarah, for her recent green wedding, which included serving guests sea bass that, contrary to some reports, was not endangered or illegally caught. Ditto to newly married couple Rebecca Romijn and Jerry O'Connell, who do their share by riding bikes anywhere they can. And to longtime farmers'-market fan Jennifer Garner, who can be spotted buying organic just about every weekend in Brentwood, Calif., and other outdoor Westside venues.

And brown thumbs down to...

Paris Hilton, for ignorantly bragging to US Weekly that she tried to order a hybrid Hummer (they don't exist, at least outside of the military). To Denis Leary, who joked, "You can take the carbon footprint and stick it up my ass. I don't care; I'm using electricity as long as I'm on this planet. I love turning stuff on, I love having giant plasmas [TVs] everywhere. If I could drive an electric car with a plasma in it, I would. I don’t care about how much electricity I'm using." Rescue him, indeed.
