Supermodel Joanna Krupa has stripped again in an effort to make animal lovers think twice before buying a puppy from a pet store. The stunner who bared all for the December issue of Playboy magazine, will be exposed for a new PETA Christmas ad campaign - even racier than the original teaser image released last week (picture below).

Krupa appears as a winged angel, covered by a carefully-placed crucifix, in the new billboard; which she unveiled outside a Barkworks store in Los Angeles earlier today.

Krupa says, "We're trying to spread the word that breeding isn't the way to go. Somebody needs to put their foot down and stop this breeding and these puppy mills... It makes me so angry that our government doesn't do anything about it. So I am!"

Check out Joanna's last PETA campaign, where she posed for three different versions of her ad:
