In honor of “Be An Angel” Day, an international, nondenominational celebration of acts of kindness, we thought we’d share some of our favorite ads starring celebrity angels for animals—including Kimora Lee Simmons, Audrina Patridge, and David Boreanaz—who have earned their wings by spreading heavenly messages about protecting dogs, cats, and other animals.

Wearing nothing but a beautiful pair of angel wings and holding her dog, Zoe, supermodel and fashion designer Kimora Lee Simmons urges people to “be an angel for dogs” in a gorgeous new ad campaign for PETA.

Kimora wanted to do the ad to show off her naked desire to get people to make dogs a part of their families—not leave them tied up outside or cooped up alone at home all day.

“You cannot just chain up an animal. The chains are heavy, it’s cruel,” she says. “Dogs need to run and play,” she adds. That’s why Kimora has teamed up with PETA urging dog guardians to “play with them, take them for long walks, don’t ever chain or cage them.

The wings Kimora wears were designed by renowned costumemaker Martin Izquierdo, the genius behind Victoria’s Secret’s iconic angel wings, who adapted his design and created Kimora’s wings out of 100 percent cruelty-free synthetic materials.

In an exclusive interview with PETA, Kimora urges people to do whatever they can to help neglected, backyard dogs. “Everybody should do the best they can,” she says, “because a lot of little bests-you-can add up to a lot of saved animals.”

Kimora has certainly earned her wings—she has donated $20,000 to PETA’s “Angel for Animals” project, which provides sturdy, custom-made doghouses for needy dogs. These dogs often have little more—and sometimes even less—than an overturned barrel or a piece of plywood resting against a fence for shelter.

To be an angel for animals today, consider giving bedding and treats to a lonely chained dog, playing with cats at an animal shelter, driving a needy animal to a spay/neuter appointment, or just giving your best friends some extra TLC.
