Pamela Anderson has declared Jessica Simpson a “bitch and whore.”

Anderson made her bold statements on an Australian radio station. Her anger comes after Simpson wore a shirt that read, “Real girls eat meat,” something that Anderson – a huge PETA supporter and vegetarian – couldn’t stand for.

Simpson’s shirt wasn’t intended to spark a feud with Anderson, but perhaps Carrie Underwood instead. Underwood used to date Simpson’s boyfriend, Tony Romo, and has frequently been on – and topped – PETA’s “Sexiest Vegetarian” lists.

Anderson, for her part, went on to tell the radio station why she was proud to be a vegetarian: “I think it’s healthy, good for your body and good for the environment.”
