LEAH REMINI is bracing for a backlash from celebrity Scientologists after quitting the church — but the “King of Queens” star has one high-profile ally who vows unwavering support.

Lisa Marie Presley, who reportedly abandoned the church in May 2012, has counseled Leah by phone and even invited her to her home in England to escape the turmoil, say sources.

The 43-year-old sitcom actress ditched the controversial religion in July.

Since then her war with the church has taken an ugly turn as she promised to write an expose and filed a missing persons report on the wife of its leader David Miscavige — a claim that Los Angeles police call “unfounded.”

A friend told The ENQUIRER that Leah fears retribution from the church, whose membership includes Tom Cruise, John Travolta and Kirstie Alley.

Shortly after Leah quit, Kirstie tweeted: "I take a moment to experience the loss of a person who I thought was my friend…then I say f*** `em."

Fortunately, Leah’s longtime pal Lisa Marie, 45, promises to be her port in the storm.

The ENQUIRER has all the details on how Lisa is saying she’s there to help Leah through her terror and a exclusive special investigation that reveals even more disturbing practices of the controversial church.
