Juliette Lewis

After struggling with substance abuse issues in her early 20s, Juliette Lewis got clean and sober with the help of Scientology, which she described as “tools for living” to Vanity Fair in 2010. “It’s about understanding one’s self and others and compassion and how to communicate better and how to live in this troubled society,” said Lewis, 42, who also tried to enlist Brad Pitt when they dated for three years until 1993. “It’s really basic, common sense stuff. It has nothing to do with all this funny folklore that surrounds it.”
