JOANNA KRUPA and PETA have the Catholic League rip roaring mad after the Playboy model and former Dancing with the Stars contestant posed as a nude angel in the latest PETA campaign promoting the adoption of homeless animals.

In the PETA ad Krupa appears completely nude, sporting only angel wings and a strategically placed crucifix with the tagline, “Be an Angel for Animals – Always Adopt. Never Buy,” encouraging pet lovers to adopt. In another ad for the same campaign, Krupa appears topless with a dog in one arm and a rosary dangling from the other.

“The fact is that cats and dogs are a lot safer in pet stores than they are in the hands of PETA employees,” Catholic League President Bill Donohue said in a statement. “Moreover, pet stores don’t rip off Christian iconography and engage in cheap irreligious claims. PETA is a fraud. Those who support this organization sorely need a reality check. They also need a course in Ethics 101.”

Krupa, a Catholic, doesn’t see it that way. “It’s understandable that the Catholic League is wary of another sex scandal, but the sex we’re talking about pertains to dogs and cats,” said the former  “Dancing With the Stars” contestant, 30. “As a practicing Catholic, I am shocked that the Catholic League is speaking out against my PETA ads, which I am very proud of. I’m doing what the Catholic Church should be doing, working to stop senseless suffering of animals, the most defenseless of God’s creation.”

In addition to Playboy, Krupa has appeared on magazine covers including FHM and Maxim, in which she was named the Sexiest Swimsuit Model in the World.
