Our fur protest at New York Fashion Week got legs when Kimora Lee Simmons stopped by. Russell Simmons' Global Grind website tweeted a lovely picture of the demonstration with a shout-out to Kimora and PETA. The fashion designer last showed off her heavenly gams for us in an ad asking people to "be an angel for dogs."

Elsewhere on Twitter, Rosie O'Donnell made us all jealous with a picture of her delicious vegan lunch.

While gearing up for his fashion week runway show, cruelty-free designer John Bartlett told one reporter, "I go crazy when I see people talking about how much they love their dog but they still wear fur—much of the fur that's coming from China is from cats and dogs."

John will fall head-over-leather-free-heels for Nicole Richie's new clothing line: It will use faux fur and fake leather.

People in New York for fashion week are no doubt seeing horses being forced to pull carriages around the city's hot, congested streets. But the horses have a new advocate: Randall, of "that crazy honey badger" video fame, has a new viral video just for the horses.

The Boss's daughter is speaking up for horses, too. New Jersey Gov. Chris Christie is reportedly a big Bruce Springsteen fan, so Jessica Springsteen is calling on Christie to sign a bill that would ban horse slaughter in the state.

Want some tea and pastries with your alt rock? Smashing Pumpkins frontman Billy Corgan is opening a tea shop in Chicago that will offer "vegan pastries from all spheres ."

After Rosie O'Donnell suffered a heart attack and discovered that one of her arteries was 99 percent blocked, she knew it was time to change her lifestyle. She cleaned her diet of animal products, watched the powerful documentary Forks Over Knives, and spoke with one of the film's driving forces (and Bill Clinton mentor), Dr. Caldwell Esselstyn. PETA also sent her a vegetarian/vegan starter kit, Paul McCartney's slaughterhouse exposé "Glass Walls," and cookbooks. Rosie is keeping her fans updated via Twitter and her blog, noting that she is losing weight and feeling healthier.

Houston Texans running back Arian Foster is getting a rush from being vegan. As the favorite to lead the NFL in rushing yards this season, he joined the celebrities who were advocating for animals on Twitter this week by posting some hilarious words for naysayers:

PeoplePets.com named its favorite "pet Tweethearts"—celebrities who fill the Twitterverse with "aww-worthy" pictures and sentiments about their animal companions. Rescue advocates Miley Cyrus and Carrie Underwood graced the list with numerous posts about their beloved dogs.

Bradley Cooper prefers to sing the praises of his rescued dog in more than 140 characters. He took his pup, Charlotte, along for his appearance on Live! With Kelly. His other rescued dog, Samson, passed away earlier this year, but we wouldn't be surprised to see Bradley and Charlotte adopting a new member into the family soon.

Missy Elliott is dropping two new singles over Labor Day weekend, but she isn't dropping her stance on spaying and neutering: Missy knows that a real "misdemeanor" would be contributing to animal homelessness by not having your dogs and cats sterilized.
