See More Celebrity Scientologists

Leah Remini's one-woman crusade against Scientology rages on in a new interview with "Larry King Now."

The "King of Queens" star has become an outspoken opponent of the controversial religion ever since she left the church back in 2013, a move she said automatically made her public enemy No. 1 for Tom Cruise.

When asked about her relationship to Cruise, Remini said: "I did know Tom. Tom is a fully dedicated and loyal Scientologist. He wouldn't say anything to me because he thinks I'm the devil. He honestly believes, and all Scientologists are taught to believe, that people like me are literally the devil, that we mean them harm."

"Tom is very well aware of what is Scientology, truthfully," she said. "He is very aware that it's an organization that is defrauding people out of their lives, but in his heart, I believe it believes it. I believe that he's, like me, has been lied to."

When asked if she thought he was "delusional," she pivoted to speaking about herself.

"I could say that about myself at the time, yes," Remini answered. "I didn't want to look, I didn't want to believe that what I was involved in my whole life was a lie, that it was damaging and hurting people. Yeah, you could say I was delusional."

Remini, who currently hosts A&E's "Aftermath," also spoke about the idea that Scientology is a celebrity religion.

"I don't think celebrities are so connected to it because if you look at the numbers, they're quite small in comparison to the majority of actors in this town," she explained.

In the show, Leah shared her experience of what happens to people who left the church, who are branded Suppressive people.

"Dealing with suppressive people means to go after them, try to destroy their lives, try to find any crimes they've committed, expose them, expose them hard. They could lie about them, they have Scientologists picketing in front of people's houses saying 'Don't trust your neighbor,' implying they he's a sexual deviant. They go after your jobs and when that doesn't work, they go after your family."

She also addressed the church's response to her claims and her new series, which they call a "work of fiction" filled with "liars."

"They should sue us, it's as simple as that, if we're lying. They say this on every outlet they can, they have said that about every single person who has spoken out and not one lawsuit has been brought to anybody and this is not a group that is scared of a lawsuit. They're a litigious group. If that were true, they would simply sue us and I welcome them to do that."

On why she thinks people still join the Church of Scientology despite her story, Remini said:

"I don't think people still join. But what I'm not gonna stand for is an organization with this kind of money to continue to do things like that and to bully people, to harass people, to defraud people out of their lives, their money, but more importantly their families. I'm not just going sit around and watch it happen."
