She’s been labelled “Suppressive” and completely ostracised by the church, but Leah Remini isn’t backing down.

Now, former King of Queens star Leah Remini is set to release a tell-all book called Troublemaker: Surviving Hollywood and Scientology that details her 30+ years in the church, as well as its influence and power over other celebrity members.

Leah Remini’s Troublemaker.

The elusive Church of Scientology is no stranger to celebrity controversy. The public escape of actress Katie Holmes with daughter Suri had many questioning what exactly goes on in this secretive religion that is home to many stars.

Speaking out is not viewed kindly and according to the Daily Mail, Remini is expecting a lot of backlash, as well as lawsuits, after this book is published. It reveals well-known celebrities’ involvement in the church, including Tom Cruise, Katie Holmes, John Travolta and Kirstie Alley.

Part of the book’s description reads:

Remini has been vocal about her time in the church since she left.

Appearing on the talk show Ellen in 2013, she spoke about the difficulty in leaving, explaining that friends were no longer able to speak to her because of the decision.

Post continues after video:

She has consistently emphasised that a large part of her decision to leave was because of her daughter, Sophia’s, involvement in the church.

In her reality TV show, Leah Remini: It’s All Relative, Remini explained, “I didn’t want to raise my daughter in the church because from what I experienced and what I saw, the church becomes everything, your mother, your father, your everything. You are dependent on the church.”

“In 10 years, if I didn’t want to be connected to the church anymore, my own daughter would be taught to disconnect from me. I didn’t want to create that. I didn’t think that would be healthy for her.”

“I’d seen a lot of crazy s**t, like crazy s**t. Like it really goes back to when I was seven years old,” she explains on It’s All Relative.

Remini is now working on the TV show The Exes and continues to keep her distance from the Church she belonged to for over 30 years.

Troublemaker will be released on November 3rd.
