Ananova:

We like nothing better than celebrities get all catty about each other.

And nobody does it better than Pamela Anderson who has slammed Jessica Simpson for wearing a t-shirt with the slogan "Real girls eat meat."

If you are not aware Pammi is a strict vegetarian and campaigner for animal rights.

It's not just all talk with the former Baywatch star either, she has recently auctioned her sports car off and donated the money to an animal charity.

Pam is currently in Australia where she is going into the Big Brother house. Just before she entered she was interviewed for local radio. When DJ Kyle made Pammi aware of Jessica's t-shirt she said: "I think she is a bitch and whore."

When radio host, Kyle, suggested that Jessica's top might have been more adult than animal themed, Anderson back tracked she added. "She was not referring to actual, you know, cows and chickens. I think she was referring to men."

She added that she is proud of not eating meat, she said: "I think it's healthy, good for your body and good for the environment."

Let's hope none of her Big Brother housemates are meat lovers.
