After he heard that New Jersey Gov. Chris Christie had weight-loss surgery, the Rev. Al Sharpton urged him to keep the pounds off the natural way: by eating healthy food and exercising. Sharpton has been all about the plants after having a chat with former President Bill Clinton, and now he's ready to help another political figure maintain his figure.

We won't be surprised if the plant-based prez is spotted dining at L.A.'s fêted new restaurant Crossroads, owned by celebrated vegan chef to the stars and PETA friend Tal Ronnen. Renée Zellweger, Warren Beatty, Ellen DeGeneres, and Tony Kanal are just a few of the famous faces you might see enjoying delectable vegan eats there.

Ginnifer Goodwin enjoyed Crossroads so much that she encouraged all her Twitter followers to check it out, and other stars were in the mood to share some of their favorite snapshots:

If you can handle even more doggie delightfulness, check out the pictures of Kevin Spacey with his new rescued dog, Boston. PETA sent Boston some toys and treats to help welcome her to her new home.

And congratulations are also in order for fur-free beauties Eva Mendes, Kristen Stewart, and Mila Kunis as well as horse hero Lea Michele and adoption advocate Amanda Seyfried. All the animal-friendly gals earned a spot on FHM's list of the top 100 sexiest women in the world.

Pierce Brosnan is no stranger to "hottest" lists—and he's no stranger to animal advocacy, either. The dashing Irishman's latest effort involves convincing the U.S. Navy to halt plans for training drills in which it would detonate explosives in the ocean, killing and injuring whales and other marine mammals.

Carrie Underwood's pretty pipes have made her one of the most influential artists in country music. But now she's piping up about something truly ugly: "ag-gag" bills. Currently being considered in several states, these unconstitutional bills would make it illegal for anyone to shoot video on factory farms in order to expose cruelty to animals, in essence making whistleblowers out to be criminals. That doesn't sit well with this vegan gal, who tweeted, "'@nytimes: Taping of Farm Cruelty Is Becoming the Crime nyti.ms/10HpjWn' What the what? Terrorism? Really? Dumbest. Idea. Ever." 

Elsewhere on Twitter, Amanda Seyfried joined multitudes of celebrities and supporters in defending PETA's euthanasia policy, Ireland Baldwin declared that she's going to go vegan (with a little help from PETA)—we sent her a vegan starter kit, Paul McCartney's "Glass Walls" video, and cookbooks to help her get started—and Leona Lewis vented about England's Grand National horse race:

We love our "Never Be Silent" campaign, and Waka Flocka Flame does, too: He never passes up an opportunity to speak up against the cruelty of fur. This time, in an interview with AOL's TheBoombox, Waka called fur "nasty as hell." We couldn't agree more.

Two and a Half Men's Jon Cryer didn't pass up the opportunity to brag about his two rescued dogs in his Us magazine "25 Things You Don't Know About Me" article. 

And over on NBC, Jimmy Fallon's Late Night audience simultaneously screamed with delight and "Awww"ed when the host talked about how überhunk Ryan Gosling has teamed up with PETA to ask for more humane treatment of cows on dairy farms. 

Hey, girl. Ryan Gosling wants you to keep up with what he's doing for animals by following @PETA on Twitter. 

Dennis Lehane – the author of bestsellers-turned-blockbusters Shutter Island, Mystic River, and Gone Baby Gone– is offering a lucrative award to the person who returns his beloved dog, Tessa. Lehane has promised to name a character in his next book after the rescuer – a book that could quite possibly become a major motion picture. Tessa jumped the fence at the Lehane home, but she is microchipped so hopefully the pup will soon have her own happy ending.

Newlywed Drew Barrymore and all her family members are living happily-ever-after. She says that her dogs, Douglas and Oliver, dote on new baby Olive: “They’re so protective of her. They’re so sweet.”

It looks like Bradley Cooper’s love of his sweet rescued dogs is rubbing off on his girlfriend Zoe Saldana.  Zoe tweeted a picture of her new rescued pup, Mugsy, and bragged, “She’s adorable and super-smart.”

The Wanted’s Jay McGuiness wants an animal-friendly date with Eliza Doolittle. “We’re both vegetarians so that’s how it works, isn’t it? It’s practically legally binding,” he joked.

All Jenny McCarthy wanted was her pre-baby body back– and she got it by going primarily vegan. “[Cutting out gluten and dairy is] the best health change I’ve ever made,” she gushed to Shape magazine. I lost a few pounds and have much more energy.”

Is Bill Clinton's healthy diet rubbing off on his wife? Secretary of State Hillary Clinton was in a vegan state of mind on her birthday, celebrating with her family and a vegan cake.

The Clintons might be a power couple for decades to come: Bob Barker names his vegetarian diet as the reason for his longevity and vivacity, telling Vegetarian Times, "I became a vegetarian out of concern for animals, and I was a vegetarian for a very long time before I realized that many people become vegetarians out of concern for their health. I think they are absolutely right. I think it is the healthiest way to live. I worked until I was 83 years old."

Ever wondered what made country cutie Carrie Underwood first ditch meat? Now we know. On VH1's Behind the Music, she described seeing her parents castrate calves. "And lightbulb," she said. "I was horrified and sad and I just couldn't believe this was happening, you know, in our pasture."

Another vegan singer, Renee Olstead, might have made a certain magazine editor cringe recently when she prominently rep'd PETA in an interview. We've had our famous run-ins with furry Vogue editor Anna Wintour, but in Renee's Teen Vogue interview, the singer and actor proudly declared, "I love animals. I'm getting ready to do a campaign with PETA. I went vegetarian when I was twelve, and I went vegan about a year and a half ago."

Staunchly fur-free Mayte Garcia just made the list of the hottest reality stars. Would her naked ad for PETA have had anything to do with that?

One of the hottest former reality stars, Lauren Conrad, has a reason to celebrate as well: She just adopted a new puppy, Fitz, from a shelter. Fitz scored some "welcome home" toys and treats from PETA to share with his new canine sister, rescued dog Chloe.

The Los Angeles City Council's vote to ban stores from selling animals who came from breeders  and puppy mills was a hot topic on Twitter this week, as were the bill that could end the Canadian seal slaughter and protecting animals during Hurricane Sandy.

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":

Natalie Portman and Benjamin Millepied wed last weekend, and to celebrate their nuptials, they feasted on vegan food at an all-vegan reception. PETA sent our friend Natalie the "Tea for Two" teapot from Daisy Dog Studio.

The U.S. has fallen for gold medal winner Gabby Douglas, but the gymnast hardly ever falls—except for animals. Answering Us Weekly's "25 Things You Don't Know About Me" quiz, Douglas' number one fact was "My favorite animals are dogs and cats." She went on to brag about having two dogs of her own.

Glee star Charlotte Ross hit it off with a chimpanzee named Burrito she met while visiting a Washington sanctuary. Chimpanzee Sanctuary Northwest, which PETA works with, is a home for chimpanzees who were rescued from animal testing facilities. Charlotte said the trip made her even more determined to see the Great Ape Protection and Cost Savings Act passed.

There was no love lost between Jane Lynch and the restaurant most notorious for bigotry and chicken abuse. Jane kicked off Comedy Central's roast of Roseanne Barr with a spirited, "F*** Chick-fil-A!" We're with you, Jane.

So is Alicia Silverstone, who joined in the Twitter conversation this week with her pro-equality, pro-chickens message:

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:

What better way to spend your birthday than being with the people you love, eating great food, and doing something good for animals! That's exactly how Carey Hart celebrated—with wife Pink and a vegan meal at San Francisco eatery Prospect. 

Beantown is a great place to be vegan, too, as Tobey Maguire confirmed while munching on nondairy sweets at vegan ice cream shop FoMu. 

Vegetarian Colbie Caillat is getting bubbly over cruelty-free skincare. The singer is the new face of Lily.B, an all-natural product line.

And beauty Pamela Anderson networked for animals on Twitter this week (as she does every week) asking her followers to help end the cruelty of the Calgary Stampede.

Bucking ropes are used to enrage animals in rodeos. The rope is tightly cinched around the animals’ abdomens, which causes them to buck vigorously to try to rid themselves of the torment.

A host of other celebs joined Pam in staying atwitter for animals:

Mariah Carey is rumored to be considering joining American Idol and bringing the show a much-needed breath of fur-free air. Years ago, when one of Mariah's fans, who clearly had more money than taste, sent her a pair of fur coats, she promptly donated the offending skins to PETA.

Fur is running out of places to hide, as Russell Simmons banned it from his news and lifestyle website, GlobalGrind.

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."
