Is Britney a Mad Cow?

Britney Spears may be going crazy from eating too many burgers and drinking too many Starbucks, according to animal rights group PETA. The anti-cruelty campaigners have written a letter to the pop wreck's parents warning them that Brit's Toxic diet could be to blame for the worsening of her reported bi-polar disorder and possible schizophrenia.

PETA quote studies suggesting dairy products and meat could be to blame for sending the singer's mental health into a tailspin.

The letter says: "On behalf of everyone at PETA, please accept our best wishes for Britney, and I hope you'll allow me to share some information that could be helpful to you in your admirable efforts to look after her mental and emotional health.

"We have heard that Britney asked for ice cream while she was in the hospital. There could, in fact, be a connection between her diet and her mental health problems. Numerous reports indicate that in bipolar patients who have hidden dairy sensitivities (a fairly common condition), the disorder can worsen if the patient consumes dairy products."

The letter then goes on to quote research that has linked parasites that are often found in undercooked meat to the development of schizophrenia.

The letter, from PETA's president, goes on to suggest that Britney go on a vegan diet to help sort out her head. We think anything is worth a try for the pop songstress right now but previous photo evidence shows Brit may find it kinda difficult to jump on the vegan bandwagon - she's a fast food fanatic!
