Animal rights group PETA is rolling out its controversial "Sex Talk" ad — in which two parents urge their daughter to have a lot of sex and "pop out all the kids you want" — in the top 10 teen pregnancy states to promote spaying and neutering of pets.

The 30-second commercial was launched in January in Britney and Jamie Lynn Spears' hometown of Kentwood, La., after news emerged of then 16-year-old Jamie Lynn's pregnancy. The "Zoey 101" star, who turned 17 in April, has since given birth to a baby girl.

"People often point their fingers at parents of pregnant teens, and we want to let the people who let their animals breed feel the heat too," People for the Ethical Treatment of Animals spokeswoman Melissa Karpel told FOXNews.com. "It's a fun, edgy way to get the message out about a very serious issue."

Karpel said 8 million companion animals are currently languishing in shelters across the United States.

Not everyone is happy about the ad, however. Karpel said the commercial is only airing in big cities in part because their markets are more likely to accept it, and some stations that were approached won't run it.

"It's certainly controversial," she said. "There have been some rejections by some stations."

The tongue-in-cheek TV spot shows a mother and father sitting down with their teenage daughter in her bedroom and telling her they have to talk about sex. She looks disgusted and embarrassed, until she hears what they say next.

"We think you should be having it, Sweetie," begins her dad.

"A lot of it," adds her mom.

"Get up there and nail everything you can," her father says.

"If it's got a pulse, you should be wrapped around it," the mother finishes.

The shocked girl asks them what will happen if she gets pregnant. They both shrug it off.

"So what?" You should pop out all the kids you want," the father replies, waving away her concerns. "We'll just leave them in the shelter, dump them in the street."

Currently, the commercial is running in Albany, N.Y.; Austin, Texas; Springfield, Ill.; Sacramento, Calif.; and Tallahassee, Fla.

In the next few weeks, it will air in Phoenix; Philadelphia; Atlanta; Raleigh, N.C.; and Columbus, Ohio.

Karpel said PETA isn't really comparing teen pregnancy with animal overpopulation, but is trying to make a point by linking the two in the ad.

"This is a way to get the message into the mainstream," she said. "It’s irresponsible to let your children have unprotected sex and it’s irresponsible to not spay and neuter your animals when we’re in an animal overpopulation crisis in the United Sates."
