Okay, I have another one. I don't know if politicians are celebrities, but I just love it that the Slovenian President, Dr. Janez Drnovsek, is vegan.
He has the guts, as a politician and leader of his country, to speak for the animals, to protest against the slaughter of animals at Christmas, saying Jesus would turn in his grave if he knew the mass slaughter of animals is carried out each year in his name, he criticises animal testing and a load of other vegan and Animal Rights stuff.
Even the dog who lives with him is vegetarian!!!
