Model and burlesque dancer Dita Von Teese shows off her curves in a racy new ad promoting spaying and neutering pets. The ad unveiled Monday in Los Angeles by the People for the Ethical Treatment of Animals stars the former Marilyn Manson flame as a corset-wearing spokeswoman for the group's ABC animal birth control campaign.

Von Teese, whose real name is Heather Sweet, is shown standing in front of a blackboard in a pink and black corset, thigh high fishnet stockings and black stiletto heels.

In the ad, a seated bookish-looking older man stares up at her.

"Nearly 4 million dogs and cats are put to death in the U.S. every year because there are not enough good homes. You can help prevent this," she says in the ad, shown on PETA's Web site.

The ad also asks people considering dog or cat adoptions to adopt from local animal shelters.

Alicia Silverstone appeared naked in a PETA commercial promoting vegetarianism which was set to run in Houston last week. The ad never aired because of its nude content, Comcast Cable Communications Inc. spokeswoman Dana Runnells told the Los Angeles Times.

Von Teese, who has gained attention as a retro fashion muse, filed for divorce from goth rocker Manson last December after a year of marriage.
