The 70-year-old is backing the Campaign which aims to end the practice of testing beauty products on animals around the world and has urged others to follow in his footsteps, reported Contactmusic.
"The ugly truth about testing beauty products on animals is that it causes them unimaginable pain and suffering. If every cosmetic tested on rabbits or mice had a photo on the packaging showing these animals with weeping swollen eyes and inflamed skin, I believe everyone would leave cruelty on the shelf and go for the cruelty-free option instead.
"So, let's stand up for those defenseless animals by supporting the Humane Society International's new Be Cruelty-Free global campaign to end animal testing of cosmetics worldwide," he said.
Animal testing for cosmetics is banned in the European Union and a further ban on the sale of cosmetics in other parts of the world is due to come into effect in March 2013, but HSI want the ban to be extended throughout the world.
