Internationally renowned primatologist and animal rights activist Dr. Jane Goodall is being honored by the Tournament of Roses as the grand marshal of the 2013 Rose Parade in Pasadena, California. The timing of the honor couldn't be better, as Chimpanzee, a film she helped make, has been popular with moviegoers and Congress is currently considering the Great Ape Protection and Cost Savings Act, which would ban invasive experiments on chimpanzees.

Fellow great ape defender Anjelica Huston is working to end fur farming in Ireland, where she grew up. Writing to Ireland's minister for Agriculture, Food and the Marine, Anjelica, who used to wear fur but ditched it after she learned about the cruelty inherent in the industry, urged him to "follow through on the commitment to add Ireland to the growing list of countries – including Northern Ireland, Austria, Switzerland, and Great Britain – that have banned the cruel practice of fur farming."

Taraji P. Henson and Elisabetta Canalis strutted their fur-free stuff this week. Taraji gave animal advocates a howling good time with her box-office–topping film Think Like a Man, and Elisabetta gave her advocacy some Italian flair, tweeting a lovely message in Italian encouraging fans to read the 20th anniversary edition of Free the Animals. 

Sophia Bush wants to free animals from military trauma training. She tweeted the link to PETA's video exposé showing goats who were mutilated, writing, "I support our troops. But I cannot in good conscience support 'training' exercises like these. This cruelty must stop."

Other celebs were all a-twitter for animals this week, too:

It looks like former Chicago Mayor Richard M. Daley took former President Bill Clinton's advice and went vegetarian, dropping some unwanted pounds in the process.

Another famous Chicagoan, Derrick Rose, introduced his new basketball shoe, the adiZero Rose 2, and the Chicago Bulls point guard is making bulls very happy—his shoes are completely leather-free.

A cobra—Cobra Starship frontman and vegetarian hottie Gabe Saporta—made the list of the 50 Most Beautiful Latinos in Hollywood, along with PETA buddies Penélope Cruz, Eva Mendes, Vida Guerra, Roselyn Sanchez, and Ana Ortiz.

Justin Bieber

Word on the street is that PETA pals Justin Bieber and Kellan Lutz will be appearing outside the Kodak Theatre on Hollywood Boulevard to promote animal adoption. 

Bob Barker

It's been a while since Bob Barker appeared on The Price Is Right, but he still wants the show he made famous to maintain his animal-friendly ideals. When the show gave away a prize of cowhide boots and a trip to the infamous Calgary Stampede, Bob wrote and told The Price Is Right it was dead wrong to promote cruelty.

Angela Simmons

Over on the opposite coast, Angela Simmons wrote to her NYC councilmember and asked him to support a ban on horse-drawn carriages that Olivia Munn, Lea Michele, Pamela Anderson, and many others have asked the city to pass.

Georges Laraque

And Georges Laraque is asking the Toronto Maple Leafs to take a pass on fur after the team promoted a jacket trimmed with coyote fur. He may have played for the opposing Canadiens, but Georges thinks both sides can agree that wearing fur is ice cold.

Ted Danson & Emily Osment

Ted Danson and Emily Osment are both showing that they are warm to animals. The distinguished actor and the burgeoning star both rave about their cruelty-free vegan eating.

"Skinnygirl" Bethenny Frankel might be calling us for tips—she is raising baby Bryn on a healthy vegetarian diet. 

Award-winning singer Leona Lewis is also a champ for seals. The longtime vegetarian and fur foe is calling for an end to the seal slaughter in Namibia. But one place that fur was welcome—and, in fact, required—was at a dog fashion show hosted by Kevin Nealon, which raised money for spay-and-neuter clinics.

Many stars have been letting their fingers do the talking, sending pro-animal messages to their millions of Twitter followers:

American Idol veteran Jordin Sparks and her four dogs would probably have enjoyed the show—Sparks makes sure that they get plenty of quality time together. The dogs travel right alongside her on her tour bus, and (get your "Awww!" ready) she says that she strives to be a better person because of them.

Is Elle Fanning thinking about becoming an animal parent too? The Super 8 star was spotted in Santa Monica looking at cats who were up for adoption.
