Leah Remini has told the Church of Scientology to ''stop f**king with people's lives''.

The 46-year-old actress abandoned the controversial church 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.

In a clip, obtained by PEOPLE, she can be seeing reading out ''just some of the things'' the Church has said about her.

One statement reads: ''A show about our religion and hosted by Ms. Remini is doomed to be a cheap reality TV show by a has been actress now a decade removed from the peak of her career. Ms. Remini, this bitter ex-Scientologist, she needs to move on with her life instead of pathetically exploiting her former religion, her former friends and other celebrities for money.''

However, Leah addresses the religion by saying: ''When you stop f**k ing with people's lives and families, I'll stop too. How does it feel?''

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.''
