Leah Remini wants to encourage others to speak out about Scientology.

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.

She 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.''

Leah previously revealed that Nicole Kidman inspired her to leave the Church of Scientology.

The 'King of Queens' actress claims the Oscar winner, who divorced the religion's most high profile member Tom Cruise in 2001, gave her the ''confidence'' to abandon her faith, even though they'd never met before.

She said: ''Nicole Kidman was an inspiration to me at the time I left the church.

''Knowing that she went on to have a successful and happy life, both personally and professionally, helped to give me confidence.

''She left and she was okay. Knowing that helped to give me confidence and comfort.''

The star - who calls Nicole her ''guardian angel'' in her book, 'Troublemaker: Surviving Hollywood and Scientology' - also claims Scientology torn Nicole's relationship with her adopted children, Isabella, 23, and Connor, 21, apart after her split from Tom.

She said: ''I felt very sad for this family, that they seemed to have been torn apart. That something outside the family had come between a mother and her children.''
