Get ready to tap your feet—the two-hour season premiere of Dancing With the Stars airs tonight on ABC, and as usual, PETA pals are strutting their animal-friendly stuff.

Just a week after she unveiled her "I'd Rather Go Naked Than Wear Fur" ad, Elisabetta Canalis will make her Dancing debut, and she's rumored to be the early favorite. When asked if Elisabetta's PETA ad would help in the competition, her partner Val Chmerkovskiy said, "I don't know if it will help us, but I do hope it helps PETA. Before I found out that Elisabetta was involved with PETA, I was astounded how conscious she was about animal cruelty and how passionate she was about helping animals involved in any sort of mistreatment."

Fellow animal advocate Ricki Lake could be a serious contender too. She proved she has determination when she was arrested after storming Karl Lagerfeld's showroom to demand that the designer stop using fur. And spay-and-neuter advocate Metta World Peace (aka: "Ron Artest") might put his fancy footwork to good use off the court and pull off an upset.

Elisabetta, Ricki, and Metta World Peace are in good company. Previous DWTS rosters read like the guest list at a PETA fundraiser. Pamela Anderson, Cloris Leachman, Steve-O, Joanna Krupa, Kelly Osbourne, Lance Bass, Jennie Garth, Audrina Patridge, Belinda Carlisle, Holly Madison, Mario, Shanna Moakler, Karina Smirnoff, and even judge Carrie Ann Inaba all know that the most important steps you take are those that help animals.

Good luck, Elisabetta, Ricki, and Ron! We'll be rooting (and voting) for you.

Mario knows what it's like to be on top—his new album, D.N.A., has been climbing the charts—but his compassion keeps him grounded. That's why this Billboard Music Award–winning R&B crooner is baring his "Soul Truth" tattoo (and his chest) in a sexy new "Ink, Not Mink" ad. And in a PETA Files exclusive interview, the soulful singer opens up about his lifelong love of animals, explains how an animal is killed for every piece of fur that is produced, and even serenades us with an impromptu tune:

Follow Mario's melodious lead by pledging to be fur-free forever.
