  Jessica Simpson

Jessica Simpson has been blasted by PETA after wearing a T-shirt bearing the slogan 'Real Girls Eat Meat'. The blonde beauty - who famously questioned why tuna was nicknamed 'chicken of the sea' on her reality TV show 'Newlyweds' - has come under fire from the animal rights group, who have urged her to become a vegetarian to increase her brain power.

A spokesperson for PETA (People for the Ethical Treatment of Animals) said: "Jessica Simpson's meaty wardrobe malfunction makes us thankful that no one is looking to her for food advice. Chicken of the sea anyone? The woman who thought that Buffalo 'Wings' came from buffalos would benefit from some good veggie brain food." However, it has been claimed Jessica wore the T-shirt to poke fun at her boyfriend Tony Romo's ex-girlfriend Carrie Underwood, who has twice been named the World's Sexiest Vegetarian by PETA.

A source said: "Jessica is sick of hearing about how Tony still has feelings for Carrie. She's obviously trying to poke fun at her rival and let her know who really has Tony's heart." Carrie is such a strong believer in vegetarianism she once said: "If you told me I could never sing again, I'd say that was horrible, but it's not my life. If you told me I could never be around animals again, I would just die."
