It doesn't take a lot to get Jenna Jameson nude.

The former porn star made an empire out of it for years. Now, in a new ad for PETA, the adult film actress is doing her best Bob Barker impression, pleading with individuals to have their pets spayed or neutered.

Doesn't staring at Jenna Jameson naked make you wanna chop the private parts off your pet? PETA is betting that it will!

Earlier this month, former Olympic swimmer Amanda Beard went nude for another PETA ad.

Call us crazy, but having celebrities take their clothes off does simply draws attention to your organization, not your cause. It's almost as though PETA is more interested in publicity for itself than it is for saving the lives of animals.

But that can't possibly be true, can it?!?
