Jenna Jameson is stripping down just four months after giving birth to twins. Just last week, the former adult film queen posed for an upcoming Playboy Magazine spread and filmed a new advertisement for People for the Ethical Treatment of Animals’ upcoming McCruelty campaign against fast food giant McDonald’s.

The 30-second ad — due next month — will see Jenna posing in a sexy strapless dress while describing the company’s slaughter of chickens.

“Chickens killed for McNuggets are slammed into metal shackles. Spinning blades meant to cut their throats often tear through their wings or bodies instead,” she says in the protest campaign.

“Many birds survive this terrifying, painful process, only to be scalded to death in de-feathering tanks. There’s a less cruel method of slaughter that renders chickens unconscious, but McDonald’s chooses to allow birds to be mutilated and scalded instead.”

Jenna Jameson previously appeared in PETA’s campaigns against Kentucky Fried Chicken and the use of fur and leather in the fashion industry.
