Leah Remini, who co-hosts Scientology and the Aftermath – the documentary series which profiles ex- Scientologists like Remini herself, and the manner in which they are shunned and targeted by the church – has claimed that Katie Holmes could lose custody of her daughter should she attempt to rekindle her friendship with Remini.

“Trust me, Katie’s not allowed to have a meal with me, and we used to be close friends,” Remini told LaPalme magazine.

“She could lose custody of Suri. It’s quite sick, really.”

Holmes famously married Tom Cruise, who is a Scientologist, in November 2006, just months after the birth of their daughter, Suri.

When Holmes filed for divorce in June 2012, though, she was granted primary custody of Suri – who reportedly hasn’t seen her father in over four years.

However, it is not just Holmes that Remini claims she is no longer allowed to make contact with: the actress previously stated that her childhood friend, Elisabeth Moss (who plays June in The Handmaid’s Tale) is similarly not allowed to talk to her.

She said simply: “Elisabeth believes that she can’t talk to me.”

Speaking to The Hollywood Reporter, Remini continued: “There’s a thing in Scientology called ‘acceptable truth.’ It means you only say what’s acceptable to the public.”

Remini added: “[Moss] believes that I'm an antisocial personality, because I've spoken out against Scientology. So she isn't allowed to talk to me.

“And me knowing that, I wouldn't put her in the awkward position.”

However, when asked how she would treat Moss at the Governor's Ball if they both won awards in their respective categories, Remini insisted that she absolutely would congratulate her.

“I don't hold anything against Elisabeth Moss other than she's continuing to support a group that is abusive and destroying families,” she said.

“That's for her to learn, just as I needed to learn it.”

Remini, who left Scientology in 2013, has made a number of abuse claims against the religious order, stating that ex-Scientologists who speak out against the religion are “harassed constantly.”

“Especially me,” she added. “Members of the Church go to my mother’s restaurant, confront my little sister, and my step kids in San Francisco, trying to intimidate us.

“These abusive scare tactics are what they call a religion!”

All claims of harassment and abuse have been vehemently denied by the Church of Scientology.

Moss, meanwhile, rarely speaks about her religion, which boasts a number of high-profile members of the Hollywood elite, other than to say that it has been “grossly misunderstood”.

“I feel it has given me a sanity and a stability that I’m not sure I would necessarily have had,” she told the press.

“But now, it’s private – off-limits.”
