PETA ripped on Jessica Simpson yesterday for wearing a shirt that read: “Real girls eat meat.” They called her an idiot. PETA writes:

For a gal who’s best known for her less-than-stellar brains (Chicken of the Sea, anyone?) and her ability to proportionately fill out daisy dukes, I’m gonna go on record saying that if anyone had to wear a ridiculous shirt like this, I’m glad it was Jessica—as people are more likely to follow the opposite of her lead … ya know, since she’s so well respected and all (yes, that was difficult to type without tossing in a hefty LOL). Maybe the meat-eaters of the world will be embarrassed to be categorized in the same field as Jessica Simpson.

OK! Magazine says the shirt is a dig at Carrie Underwood, Tony Romo’s ex, who is a devout vegan.

“Jess is sick of hearing about how Tony still has feelings for Carrie,” says the insider. “She’s obviously trying to poke fun at her rival and let her know who really has Tony’s heart.”

PETA is missing the sexual innuendo, but that’s fine because PETA is gay. According to them, these are the top five reasons “stupid girls brag about eating meat.”

1. Meat increases the risk of breast cancer.
2. Real girls don’t support animal abuse.
3. The meat industry is destroying the Earth.
4. Meat will make you fat.
5. Eating meat steals food from starving kids.

Whatever. If you want to be vegan, that’s fine with me, but don’t tell me how bad meat is because it’s falling on deaf ears. Meat is awesome. I eat meat all the time. Bacon for breakfast, genetically enhanced chicken for lunch, hormone injected steak for dinner and then end the day with a blended meat shake. Mmm. Afterwards, I like to lie down on the floor and prepare for the ensuing heart attack. Life is good.

Did Jessica Simpson try to start a food fight with Tony Romo’s ex Carrie Underwood?

The singer, 27, wore a “Real Girls Eat Meat” T-shirt (which she got for free from steakhouse Primehouse New York) during a weekend outing with Romo, who dated Underwood in 2007.

Underwood was named PETA’s Sexiest Vegetarian in 2005.

PETA quickly jumped to Underwood’s defense.

“Jessica Simpson’s meaty wardrobe malfunction makes us thankful that no one is looking to her for food advice. Chicken-of-the-Sea, anyone?” a PETA rep tells Joynews. “The woman who thought that Buffalo ‘Wings’ came from buffalos would benefit from some good veggie brain food.”

Adds the rep: “We’re rushing Jessica one of our Vegetarian Starter Kits.”

Pamela Anderson may have a need for speed, but her favorite charity has a need for funds.

That’s why the former “Baywatch” babe is selling her prized Dodge Viper and donating the proceeds to People for the Ethical Treatment of Animals.

“I’ve been working with PETA for 15 years,” Anderson told The Associated Press. “They’re kind of my ethical advisers. With them, I see actual results.”

The 40-year-old actress recently held a private estate sale to benefit the animal organization, and she’s planning to personally oversee the sale of her 2000 Viper, which she customized herself with white racing stripes. The car plays a prominent role in Anderson’s forthcoming E! series, “Pam: Girl on the Loose,” but she admitted it was dangerous for her to own such a high-performance vehicle.

“I’m a terrible driver,” she said. “It’s just not a good idea for me to have a Viper.”

The car will be among the offerings at Julien’s Auctions’ Summer Entertainment Sale of Hollywood memorabilia, to be held June 21 and 22 at the Planet Hollywood Resort & Casino in Las Vegas. Other items available include Alfred Hitchcock’s driver’s license, personal snapshots of Marilyn Monroe and Sammy Davis Jr. and an original “Ben Hur” script signed by Charlton Heston. The sale will be broadcast live on Auction Network.

Though Anderson regularly attends charity auctions, she said she’s not much of a collector.

“I get sports stuff for my kids,” she said. “But me? I, just on a whim, give everything away. This is another one of those opportunities, but it’s specific. It goes to the cause.”
