* JAMESON STRIPS FOR PETA SEX AD Former porn star Jenna Jameson is baring all in a sexy new PETA ad to urge pet owners to get their dogs and cats spayed and neutered. The sexy actress, who is expecting her first child with boyfriend Tito Ortiz, poses seductively wearing just a white bed sheet to cover her assets. In the ad, she warns, "Sometimes too much sex can be a bad thing." Jameson tells WENN, "Until dogs and cats can go on the pill or wear condoms, we need to help them practice safe sex by spaying and neutering. "Millions of homeless animals are turned in to shelters every year because there simply aren't enough good homes for them all. The answer is as easy as ABC: animal birth control, which means get Fido and Fluffy fixed!" (KL/WN ) This is a PR photo. WENN does not claim any Copyright or License in the attached material.
