As the Discovery Channel wraps up its annual Shark Week, TOMS Shoes is making it Shark Year. The philanthropic footwear company created a pair of shark-silhouette–lined shoes, with proceeds going to protect these often misunderstood, abused animals.

If the vegan shoe fits, wear it. Former Miss World Rosanna Davison is trading her stilettos for running shoes, training for Ireland's Ironman Triathlon. She's also trading her vegetarian diet for a vegan one, and she tweeted, "I absolutely LOVE it & have never felt better! I recommend it to so many people."

Mischa Barton is raving about her vegan diet, too, noting that healthy food and regular exercise have given her the body she wants without having to count calories.

Another great way to get in shape while helping animals? Running with the PETA Pack. Jillian Michaels and Renee Olstead were among the animal-friendly celebs running to Twitter this week, with both gals encouraging everyone to start "packing":

There isn't a chick alive who doesn't love Ryan Gosling, from the ones he woos in theaters (guilty) to the ones he helps on factory farms. He was spotted saving the latter recently by eating vegan at Los Angeles' Flore Vegan Cuisine.

Since animals aren't normally allowed to go to concert venues, Jay Sean invited them into his living room. The rapper performed an online Stageit show from his home and donated all the proceeds to PETA's "Angels for Animals" program, which provides neglected, chained dogs with doghouses, toys, and lightweight tie-outs.

On a slightly larger screen, Bones is set to air another animal rights–themed show. Vegan star Emily Deschanel says she loves hearing from fans that the Bones episode on chicken farming made them stop eating chickens, and now the Fox thriller is tackling the exotic-animal smuggling trade. 

Fran Drescher is hopping on the vegan train as well, telling RadarOnline about some of her delicious recipes: "Lately, I have been eating vegan and gluten-free, so I have been making delicious kale soup and gluten-free pasta with sautéed arugula, garlic, olive oil and pesto. I also like my recipe for white bean hummus, as well as a good simple field and micro green salad with my special house dressing of olive oil, lemon, Dijon mustard and salt and pepper. I like to add raw veggies to it, like peas, corn, carrots, and zucchini."

James Cameron is growing vegan. The director just purchased 2,500 acres of rural land in New Zealand, and part of his property includes a former dairy farm. The government is requiring Cameron to continue to farm on part of the land, and the director, who grabbed a PETA Proggy Award for Avatar, said that since he and his family are striving for a more plant-based diet, they will likely grow crops. 

Cameron is no stranger to awards, and neither is our friend Kate del Castillo, who snapped up several of Telemundo's nominations for its inaugural Premios Tu Mundo Awards.

Other celebs were busy representing animals in the Twitterverse this week:

When former English soccer player Michael Owen ran his leg of the Olympic torch route, he got some help from a special guest—a dog up for adoption at a London animal shelter. The now-famous dog, named Rory, may not be homeless much longer.

Marathoner Michael Arnstein is also giving animals props at the Olympics—he fuels up only on vegan foods. 

Legendary basketball player John Salley will soon be flashing his charming smile all over Detroit. He is just one of the faces of the "Real Vegans" billboard campaign, by nonprofit VegMichigan, which aims to show people how easy and healthy vegan eating can be.

In fact, it's so easy and healthy that vegan eating is heading to the final frontier. NASA announced plans for an all-vegan menu for its astronauts who are setting out for a mission to Mars in 2030.

Bob Barker is sending three elephants on the journey of their lives. The longtime PETA friend is flying Iringa, Toka, and Thika from the Toronto Zoo to the Performing Animal Welfare Society sanctuary in California, where they will get to retire in spacious comfort.

It was a flight of a different sort that had America's Next Top Model alum Natasha Galkina speaking up for animals this week. After she read about PETA's campaign to get United Airlines to stop shipping monkeys to be tortured in laboratories, she tweeted her disgust at the airline, adding to the chorus of animal-friendly voices on Twitter:

Things got rockin' at our "Summer Is No Vacation for Animals on Fur Farms" demonstration in Portland, Maine, when Gavin Rossdale and his son Kingston stopped by:

Gavin thanked the demonstrators for being there and mentioned that he and his fur-free wife, Gwen Stefani, are teaching their children to be kind to animals.

Chad Ochocinco (whose sizzling PETA anti-fur ad might be part of the reason why he's considered "the ultimate catch") tied the knot last weekend with fiancée Evelyn Lozada. So PETA sent the happy couple—what else?—an elegant faux-fur throw from Donna Salyers' Fabulous-Furs. 

Fur foe Lea Michele is being recognized for her animal activism. She earned a 2012 Do Something Award nomination for her work with PETA to shut down New York City's cruel horse-drawn carriage industry. Be sure to cast your vote here! 

PETA pals are snagging nominations right and left this week. Eva Mendes, Penélope Cruz, Benicio Del Toro, Roselyn Sanchez, Martin Sheen, and Constance Marie are all nominated for 2012 National Council of La Raza ALMA Awards. 

And vegetarian wrestler Austin Aries just claimed the title of TNA World Heavyweight Champion.

When 11-time Olympic medal winner Natalie Coughlin heads to London, she'll have some new reading material for the plane. PETA sent the swimmer vegan cookbooks and a vegetarian/vegan starter kit to help her maintain her nearly 100 percent vegetarian diet on the road.

NFL star Arian Foster is hopping on the vegan-athlete bandwagon. His inspiring tweets were some of the best in the Twitterverse this week:

Dominic Monaghan also took to Twitter to defend animals this week, calling the show Swamp People, which glorifies the killing of alligators, "death entertainment" that "continues to demonize reptiles as monsters and animals that are okay to torture and kill." He then vowed, "I'm gonna stop them."

Bob Barker is ready to put a stop to the Calgary Stampede. Everyone's favorite game show host said of the cruel 10-day rodeo festival, in which three horses have already died this year, "I would like very much to see them celebrate the 100th anniversary of the Calgary Stampede by saying that is enough animal cruelty. Let's wind it up and close it down."

When the Olsen twins—the "Trollsens," as PETA calls them—trotted out a fur backpack, there wasn't a chance that Running Russell Simmons star and animal advocate extraordinaire Simone Reyes was going to let it pass without a comment. She blasted the Trollsens on her blog, saying that they are "unfortunately using their vanity and the pursuit of making a blessed buck at the expense of innocent sentient beings." Russell Simmons jumped in to help, tweeting Simone's blog.

The Trollsens could take a cue from Banana Republic, which is launching a line inspired by the costumes in the upcoming film Anna Karenina that will be designed with elegant velvet, lace, and faux fur.

You won't catch Constance Marie wearing animals or gawking at them in the rodeo ring. She tweeted, "Please boycott rodeos! #Video shows #Reno rodeo horses being shocked to perform: bit.ly/LLoUot #CrueltyIsNotEntertainment."

Horror movie king Eli Roth knows that what's really horrific is when animals are abused for entertainment. He tweeted in defense of elephants: "Elephants need you! Urge the Atlanta City Council to pass a total bullhook ban! bit.ly/LFIivF #NeverBeSilent."

Olympian Michael Phelps adopted his new pooch, Stella, and promptly started honing her ability to swim. We're sure Michael already qualifies as a hero to Stella even before the London games!

Paul McCartney has schooled many a musician in rock 'n' roll, and now he wants to school children in going vegetarian. He's encouraging schools to join his "Meat Free Mondays" campaign and offer students vegetarian options at lunch.

Black Swan director Darren Aronofsky and Switched at Birth actor Constance Marie joined Paul's chorus, jumping in with the host of other celebs tweeting for animals this week and promoting "Meat Free Mondays" and the veggie life.

The role of WNBA star Candace Parker in the L.A. Sparks' win last Wednesday earned her a Player of the Week nod, but she plays for animals every week by working with PETA to fight fur.

With another fur foe, Aimee Teegarden, cast in the starring role, you can bet that the CW Television Network's new show, The Selection, billed as "the next Hunger Games," will be decidedly fur-free.
