Leah Remini Makes Shocking Claims About Suri Cruise in New Book

Leah Remini is baring all in her new book.

According to an advanced copy obtained by the [New York Daily News](https://www.nydailynews.com/entertainment/gossip/leah-remini-rips-scientology-new-tell-all-book-article-1.2418961?utmsource=Sailthru&utmmedium=email&utmcampaign=Daily%20Newsletter%202015-11-01&utmterm=DailyNewsletter), the 45-year-old actress is making shocking claims about Tom Cruise and Katie Holmes' daughter, Suri Cruise, in her Scientology tell-all.

In her book — titled Troublemaker: Surviving Hollywood and Scientology — Leah reportedly details a dinner party held before Tom and Katie's November 2006 wedding where a then-seven-month-old Suri was left to cry on a bathroom floor while her parents showed no concern for her well-being.

Leah also recounted spending an awkward car ride with Tom's older children, Isabella and Connor. When the The King of Queens star asked the kids if they'd recently seen or planned to visit their mother, Nicole Kidman, Isabella replied, "Not if I have a choice. Our mom is a f—ing SP."

"SP" reportedly refers to a "Suppressed Person," Scientology terminology for an individual who has turned away from the religion and is thus considered an enemy by those still following the church's teachings.

Tom, 53, and Nicole, 48 — who adopted Isabella, 22, and Connor, 20, as infants — were previously married for 11 years from 1999 until 2001. The actress has been reluctant to discuss her past involvement in Scientology since her divorce, though she has admitted she supports her children following the church. The Mission: Impossible star and Katie, 36, were married from 2006 to 2012. Katie reportedly divorced Tom after six years of marriage to protect Suri, 9, from Scientology.

Leah's book Troublemaker: Surviving Hollywood and Scientology hits shelves on Tuesday, Nov. 3.
