Afer having lunch with friends at the trendy Cuvee Cafe, Audrina Patridge was all smiles as she strolled down Robertson Blvd. in West Hollywood today (April 21).

Waging on with her post-Hills career, A.Pat is PETA’s new angel after signing up to play a cherub in a new animal adoption poster ad.

The former reality TV starlet will appear in a white bikini and angel wings, holding her rescued dog Speedy Gonzalez in the new campaign, which debuts in L.A. on tomorrow.

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

Cautions Miss Patridge: “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.”

Stay tuned for the big debut tomorrow!
