20 Well-Known Celebrities Associated With Scientology
Hollywood has always been a place where spirituality meets stardom, and one organization has captured the attention of many famous faces over the decades.
Scientology, founded by science fiction writer L. Ron Hubbard in the 1950s, has attracted actors, musicians, and public figures who credit it with transforming their lives.
Some remain devoted members today, while others have stepped away and shared their stories with the world.
