The Hills star Audrina Patridge is animal rights group Peta's new angel after signing up to play a cherub in a new animal adoption poster ad. She'll appear in a white bikini and angel wings, holding her rescued dog Speedy Gonzalez, in the new campaign, which debuts in Los Angeles Today.

The poster aims to alert potential pet owners to give homeless animals a second chance, rather than buy dogs and cats from pet stores.

Patridge cautions, "Buying animals means killing animals... Each year, six to eight million unwanted dogs and cats are turned in to shelters, and half are killed because there aren't enough good homes."

She also urges pet owners to spay and neuter dogs and cats to prevent unwanted births.
