You won't catch Abbie Cornish in fur—or any other animal skins. When asked about her style on Twitter, Abbie responded, "I LOVE clothes … So I love so many different things. Not enough room to tweet! I dress vegan … no leather, suede or fur."

Elsewhere in the Twitterverse, we had animal adoption, a heroic rescue, and vegan chocolates.

Animal-friendly celebrities had a blast showing off their big hearts (and vegan stomachs) this week: Courtney Stodden at the beach with PETA's Vegan College Cookbook, Anne Hathaway at another fun vegan engagement party, and vegan Venus Williams chatting with CNN about the London 2012 Olympic Games.

?uestlove is on a quest to live longer. The Roots star said he is going vegan so that he can be "the first member of the hip-hop generation to live past 60."

Congrats to the animal-friendly cast of The Secret Life of the American Teenager. Season five—starring our buddies Megan Park, Renee Olstead, and, new this season, Twilight's Christian Serratos—premiered to rave reviews.

From Hollywood to Wimbledon, it's clear: Everybody's going vegan.

Mischa Barton said she dropped weight when she dropped animal products, and vegetarian Alan Cumming was inspired by vegan Mike Tyson to do all animals a solid and go vegan too.

Venus Williams' new vegan diet is helping her manage her Sjögren's syndrome. Little sis Serena Williams followed in Venus' tennis shoes and went vegan as well. And WWE champ CM Punk made it his New Year's resolution to C Meat out the door.

Roselyn Sanchez asked people not to light fireworks, which terrify animals and kill birds, on New Year's Eve. Then she started her year off with a bang, welcoming a new little animal advocate, daughter Sebella Rose Winter, to her family.

UFC Fighter Dan Hardy is welcoming fellow fighter Matt Hughes to the ring to pick on someone his own size. Hardy called Hughes out for hunting for sport, tweeting, "There is no justification for what he does. I fight against other people that enjoy fighting also. Shooting animals for fun isn't sport and it certainly isn't cool."

What is cool is keeping up with what  celebs are doing to help animals by following PETA on Twitter.
