EXCLUSIVE: Jenna Jameson Does Playboy, PETA & Peeves Off McDonalds

Only four months ago, Jenna Jameson welcomed twin boys into the world and already the retired porn princess has dropped those pregnancy pounds, is back in tip-top shape and doing what she does best — taking her clothes off.

Pop Tarts has exclusively learned that Jameson shot quite the sexy campaign for Playboy Magazine in Los Angeles on Thursday evening, but in between takes for her upcoming spread the adult superstar took a stand by shooting a new ad for PETA's McCruelty campaign against McDonald's. Although Jameson donned a sexy strapless dress, she is bound to turn you off your Happy Meal.

"Chickens killed for McNuggets are slammed into metal shackles. Spinning blades meant to cut their throats often tear through their wings or bodies instead,” Jameson said in the 30-second spot which is set to hit the airwaves this Fall. “Many birds survive this terrifying, painful process, only to be scalded to death in defeathering 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."

A rep for McDonalds did not respond for comment.

But back to something almost as important, like Jameson’s sensuous structure, the starlet credits her strict vegetarian diet , “healthy” relationship with her man Tito Ortiz and oddly enough, paddle-boarding for bringing back her pre-preggo body.

Warner Bros. Under Fire Over 'Irresponsible' New Horror Film Targeting Adopted Children

Warner Bros. new horror flick “Orphan” may be causing its audience to scream, but it is also causing a squeal from a growing number of national adoption groups and organizations who are urging Americans to boycott the flick which is centered on an evil adopted child.

Leading philanthropist and founder of Children Uniting Nations which supports foster youth, Daphna Ziman, is one of the many who are outraged and joining the charge to promote a socially responsible solution.

“Although we recognize the film is fiction, the response we have had from adoption groups and potential adoptive parents has been overwhelming,” Ziman told Tarts. “When a major corporation sensationalizes on an area that affects our nation's most needy children without responsible messaging it is unconscionable. Warner Bros. needs to be socially conscientious of the children they are potentially harming and put a disclaimer on the film and a public service announcement educating viewers on the plight of children living in protective custody through no fault of their own.”

Advocacy groups believe that the film may feed into any possible pre existing doubt and prevent parents from adopting. Although Warner Bros is yet to meet Ziman’s request for a meeting with executives to add the disclaimer, the studio has reportedly removed a highly criticized line from the film where the orphan Ester says, “It must be hard to love an adopted child as much as your own.”

“'Orphan’ is a work of fiction; it is not a depiction of any real-life events or situations and has never been portrayed as anything but an entirely fictional story,” a rep for Warner Bros told Tarts in response. “We apologize if we appeared insensitive with the initial trailer as it's never our intent to offend anyone with our products.”

K-Fed is K-Fat & Financially Tight

Despite the fact Kevin Federline is earning around $30,000 a month in child support from ex wife Britney Spears, Pop Tarts has been told that the backup dancer turned reality star failed to tip the cocktail waitresses even a single penny at the Hard Rock Hotel & Casino’s Wasted Space on Thursday night even after being given two complimentary bottles of Grey Goose.

After wrapping up his new VH1 reality show, a particularly heavier Federline partied hard with yesterday girlfriend Victoria and a group of 15 friends while his VH1 stage crew spent most of the night filming while sipping cocktails. At one point K-Fed decided he wanted to draw more attention to himself and got on stage to hype the Sin City crowd, bragging that he was intoxicated. Fed and his we-don’t-tip posse left the club around 3 a.m., when they reportedly moved on to party in the new Paradise Tower Mega Suite.

But on the brighter side, Brit’s conservatorship is up for review and November and she may very well be her own boss again — and perhaps one step closer to regaining custody of her two sons.
