At long last! Jenna Jameson has finally gotten naked!

Kidding aside, the ever-juicy Jenna, star of the recent DVD release Zombie Strippers, is appearing in a brand-new ad for PETA. In addition to rather going naked than wearing fur, Jameson is stripping to promote spaying and neutering your pets.

Never before has the idea of a scalpel hovering near one's genitals looked so sexy!

We can't help but wonder if Bob Barker is kicking himself right now for not thinking of going nude save for a strategically placed pillow to promote animal rights.

Then again, we'd much rather play Plinko with Jenna.
