Actress Leah Remini quit the Church of Scientology in 2013, and has since been a vocal critic of the controversial religion.

Remini told FOX News' Megyn Kelly that she wouldn't have been able to do her new docuseries, "Leah Remini: Aftermath," without the support of her friends in Hollywood.

"It's not really scary for me [to speak out]," Remini told Kelly Monday night. "I'm lucky enough to be in this business and have the support of all of you in the media that I can speak about it."

She continued, "What is scary is that...this is an organization, a place supposedly of worship calling itself a church, that systemically goes after people that speak out about it and that's why I wanted to do this."

The Church released a statement criticizing the actress, saying she "needs to move on with her life and career and stop blaming the Church and others for all of her personal and professional setbacks... 'Leah Remini: Aftermath' is really 'Lear Remini: After Money.'"

The former "King of Queens" star also spoke about being reprimanded at Tom Cruise's wedding for questioning the whereabouts of the wife of Church leader David Miscavige. She called it an eye-opening experience.

"I was told I didn't have the effing rank to ask where a human being was. That really did start the ball rolling," she said. "Because as a parishioner, as someone who was promoting and defending this church, I have a right to ask where a human being is regardless of my rank in the church."
