The 46-year-old actress abandoned the Church of Scientology in 2013 after 30 years and has been working on a new A&E docuseries 'Leah Remini: Scientology and the Aftermath' in order to expose it and says Tom and other members of the church see her as the enemy.
In an interview for 'Larry King Now', she said: ''He thinks I'm the devil. Tom and most Scientologists, all Scientologists, are taught to believe that people like me are literally the devil, that we mean them harm.
''Tom is a dedicated and loyal Scientologist. Tom is very well-aware of what is Scientology, truthfully. He is very well-aware that it's an organisation that is defrauding people out of their lives. But in his heart, I believe he believes it.''
When asked if she thinks Tom is ''delusional'', Leah said: ''I could say that about myself at the time.
''I didn't want to look. I didn't want to believe that what I've been involved in my whole life was a lie, that it was damaging and hurting people. Yeah, you can say I was delusional.''
Speaking previously about her reason for making the documentary, Leah said: ''For too long, this multi-billion-dollar organisation bullied victims and journalists to prevent the truth being told. It is my hope that we shed light on information that makes the world aware of what is really going on and encourages others to speak up.
''Even though I had been a member of the church for a long time, I was stunned by some of the things I learned. There is a lot more to this story than anyone knows. And this series is breaking ground in bringing that information to light.''
