Audrina Patridge was no angel on The Hills the other night, making eyes at Brody Jenner while his girlfriend, Jayde Nicole, was far from pleased.

But the reality star has certainly earned a set of wings (which look great with that sexy white bikini, if you ask us) in her new campaign for PETA!

On a billboard set to be unveiled today on L.A.'s Beverly Boulevard, Audrina Patridge poses in a provocative angel outfit with her rescued dog, Speedy Gonzalez, next to the line, "Be an Angel for Animals-Always Adopt, Never Buy."

Audrina Patridge looks so good in this ad, we'll forgo the usual PETA wise cracks. We much prefer Speedy Gonzalez to that other dog she's often seen with, Justin-Bobby.

In a statement released by PETA, Audzo says, in support of the animal rights group, "Each year, 6-8 million unwanted dogs and cats are turned in to shelters, and half are killed because there aren't enough good homes."

"The solution to this problem is as easy as ABC - animal birth control. Always spay and neuter, and never buy from a pet store or a breeder."

Good for her for supporting a good cause. Check out spoilers and pics of Audrina and the rest of the cast of the hit show at yesterday's Paley Fest!
