From www.foxnews.com- They garnered fame as “Penthouse Pets” but now the men’s magazine centerfolds have opted for a different approach and are posing with their pets — all in the name of charity.

Mia Presley [pictured] has joined forces with about 70 adult models and stars (including infamous x-rated film director Ron Jeremy ) to raise funds and awareness for numerous doggy rescue centers across the country by hosting parties and selling autographed pics of the pets — with their pets.

“Models love animals and most of us have warm hearts,” Presley told Tarts in an exclusive interview. “Everyone thinks we’re divas but we’re just nude models. We’re high class, hard-working and giving sexy a smart voice. I’m not ashamed of anything I’ve done.”

Interestingly, Presley said that the stereotype of porn princesses having fake everything these days is a total myth (she’s proudly flat-chested and says she has never gone under the knife).

“The industry is changing and a lot of girls feel the same as me,” she said. “Being all-natural means we can cross-over and do mainstream work as well.”

But that’s not the only shift in the adult arena; it seems it’s no longer men at the forefront of the fan base.

“I have more women that recognize me and come up to me,” Presley added. “Most of the time it’s pretty positive, they feel empowered by what I do.”

Speaking of women infiltrating a traditionally male world, a recent survey conducted by British paper The Sun showed that 66 percent of females watch porn on a regular basis.
