The environment, gas prices, etc., are giving drivers more incentive than ever to consider the alternatives, it’s a good time to review all the celebrities who have already taken the plunge with the most famous alternative: the Toyota Prius Hybrid.

Celebrity Toyota Prius Drivers…

Among the first famous Prius drivers is early adopter Leonardo DiCaprio, who’s been driving one since 2001 when they were new. Then Cameron Diaz got one. Then, like, EVERYBODY got one. “Everybody” includes usual green and/or lefty celeb suspects like: Alicia Silverstone , Arianna Huffington, Brad Pitt, Julia Roberts, Bill Maher, Prince Charles, Woody Harrelson, Harrison Ford, Ed Begley, and Susan Sarandon.

But now the Prius is common enough that less-expected Prius owners in Hollywood number easily in the dozens (maybe more like hundreds), including Kevin Bacon, Jack Nicholson, Billy Crystal, Larry David , Ewan McGregor, Robin Williams, David Duchovny, Alexandra Paul, America Fererra, Billy Joel, Dr. Andrew Weil, Ted Danson, Will Ferrell, Salma Hayek, Patricia Arquette, David Hyde Pierce, Ellen DeGeneres, Tom Hanks, Rob Reiner, Hart Bochner, Donny Osmond, Kurt Russell, Jack Black, Donna Mills, and Kirk Douglas. The jury is still very much out on whether the Prius is the best (or even a good) green car option, but it is certainly the most recognized.

Celebrity Ford Fusion Drivers… American Idol runner-up Adam Lambert loves his new hybrid. Lambert says, “Hybrid all the way. Let’s protect the environment.” He may not have won first place on American Idol, but runner-up Adam Lambert is happy anyway, especially since he was given a Ford Fusion Hybrid. Lambert and winner Kris Allen each received hybrid cars from the Ford Motor Company.

Backstage after last night’s American Idol finale, Lambert was all smiles, psyched about getting to sing with Queen and KISS. Asked if he was happy with his Ford Fusion, Lambert replied,

“The Fusion is beautiful. It’s so whisper quiet. Hybrid all the way. Let’s protect the environment.”

Hey, rolling through Los Angeles in a Ford Fusion hybrid is a pretty good consolation prize!
