Forks Over Knives continues to change the way that America eats. Kristen Bell and fiancé Dax Shepard have both gone vegan after seeing it.

Another awesome Kristin—Kristin Chenoweth—is throwing her support behind her Glee costar Lea Michele's campaign to get horse-drawn carriages out of New York City. Chenoweth tweeted her disgust at seeing the miserable horses and is asking the New York City Council to ban the carriages.

Anjelica Huston is taking a stand against horse-drawn carriages while working in New York. The Smash star criticized the cruel carriage industry on Piers Morgan Tonight, and guest host Rosie O'Donnell agreed, "It does seem absurdly cruel." Anjelica continued speaking out for animals, deeming it "unconscionable" to orphan baby apes and force them to act.

And as always, Ricky Gervais continues to keep Twitter abuzz for animals, this week posting, "you can't justify torturing an animal for a shampoo."

Steve-O agrees that animals don't belong in laboratories. He wrote to U.S. Sen. Barbara Boxer of California to ask her to support the Great Ape Protection and Cost Savings Act, which would ban the use of chimpanzees in experiments.

Fellow vegan and tattoo aficionado Travis Barker is raising health-conscious, animal-friendly kids who share their dad's penchant for vegan eating.

Nikki Reed and husband Paul McDonald welcomed a new "kid" into their family—a beautiful rescued dog.

Michael Vick's last-minute cancelation of his scheduled February 24 appearance on Oprah is all over the news, and the big question everyone's asking is, "Why did Vick back out?"

PETA pal Simone Reyes tweeted her theory: "Rumor has it @Peta was prepping @oprah w/ the tough questions for Vick." We can't blame Vick for fearing the grilling he might have received from an avowed dog lover and PETA's 2009 Person of the Year, but, so far, the only explanation Vick has given for canceling is that it was for "personal reasons."

Hopefully, Vick will take the advice of Los Angeles Times blogger Joe Flint, who wrote yesterday, "Part of what Vick needs to learn and show is humility, and going on a popular TV show to say look at me now is not humble." But in case Vick decides to try his luck with Piers Morgan (who lost a $300 bet with Oprah that he would be the first to snag Vick for an interview), PETA president Ingrid E. Newkirk has already sent Piers a friendly e-mail asking him not to book Vick on his show.
