Ne-Yo is making it a happy New Year for animals: The rapper has resolved to go vegan in 2013. When Ne-Yo first tweeted his New Year's resolution, he deemed it a discipline test. But after he learned about the cruelty of the meat and dairy industries, he said that there was "much more meaning to it." PETA sent him vegan dining expert chef Tal Ronnen's The Conscious Cook: Delicious Vegan Recipes That Will Change the Way You Eat, a vegetarian/vegan starter kit, and fellow music legend Paul McCartney's meat industry exposé, "Glass Walls." 

Ne-Yo has been keeping his Twitter followers up to date on his progress and has received an outpouring of support, as have animals:

Maybe Ne-Yo will give Anderson Cooper the inspiration that he needs to help him make the switch. When Anderson invited vegan Alan Cumming onto his show, the pair noshed on meat-free chicken wings and Anderson talked about his vegan aspirations.

PETA friend Kelly Osbourne says it was her boyfriend, vegan chef Matthew Mosshart, who helped her drop pounds and feel better. "That's because he cooks for me! He's a vegan chef so he makes sure I eat healthily," she says. "I'm happy with how I look now."

Emma Stone and Andrew Garfield are happy with how their family looks now, with the addition of their new rescued dog, Ren. They took the pup in as foster parents, but it took the couple only a few days to make it official. PETA sent Ren a homecoming present of treats and toys.

PETA's 2010 Sexiest Vegetarian Celebrity Olivia Wilde and shelter dog advocate Emma Stone have another (synthetic) feather to put in their nonwool caps.

The ladies each earned a PETA Kind Choices Award for promoting cruelty-free cosmetics from Revlon, one of the first cosmetics companies to ban all animal testing. 

Olivia and Emma are gorgeous living proof that women can save animals' lives with every mascara, eye shadow, and blush product they purchase. In addition to Revlon, hundreds of other companies, including Almay, Kiss My Face and ELF, refuse to test their products on animals. Check out PETA's handy cruelty-free guide for the complete list.

Fighters, schmighters―after Jake Shields' recent tweet, the people he'll really need to shield himself from are all the clamoring vegan girls. And they're probably in pretty good shape, too, if they've been fueling up on the healthy fare that Ellen DeGeneres shares on her website's "Go Vegan With Ellen" page. Hope they leave room for Anne Hathaway's luscious vegan treats.

Alicia Silverstone is raising a little vegan Bear, of course. Maybe she has some words of wisdom for cruelty-free mom-to-be Emily Deschanel?

And PETA has words of wisdom for Diane Kruger, about her photo shoot in which she was draped in coyote. Hasn't she heard it's better to go naked than wear fur? Furry Alexander McQueen may have passed on, like so many of the animals he killed for clothes, but at least he did make a kind decision in his will. Where was his compassion when he was alive?

Well, it's very obvious where Bree Olson's compassion is―you can't miss it. And Olivia Wilde and Emma Stone are going to have cruelty-free written all over their faces.

Emma Stone, star of the upcoming Spider-Man film, was recently snapped by photographers cuddling and walking a fetching little black-and-tan dog outside a Los Angeles doggie daycare, grooming service, and nonprofit dog rescue center. Some reports say that Stone was dropping her pooch off for grooming, while others maintain that she had just adopted the dog from the center.

Either way, it's awesome that Stone supports rescuing companion animals. Wonder if she and Penn Badgley talked about the joys of saving homeless animals on the set of Easy A …
