Audrina Patridge is an Angel for PETA

Audrina Patridge of The Hills is the latest celebrity to pose in a PETA “Angel for Animals” ad.

The reality show star appears in a white bikini and angel wings and holds her rescued dog Speedy Gonzalez next to the tagline "Be an Angel for Animals—Always Adopt, Never Buy."

"Each year, 6 to 8 million unwanted dogs and cats are turned in to shelters, and half are killed because there aren't enough good homes," says Audrina.

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

Audrina's sexy billboard will be unveiled today in Los Angeles around noon on Beverly Boulevard, between Sweetzer Avenue and Harper Avenue. So if you happen to be in the area, feel free to swing by--and tell them Hollyscoop sent you!
