John Travolta is a proud Scientologist, and, quite frankly, he doesn't really care when others badmouth the religion.

Late last month, A&E premiered Leah Remini's docu-series, "Leah Remini: Scientology and the Aftermath." In the series, the actress and former Scientologist paints the religion is very negative light, and accuses the Church of Scientology of abuse, lies, sexual misconduct and family abandonment.

John, though, said he's "not interested" in the program or in finding out what others have to say.

"It's been nothing but helpful to me for 40 years, through all my losses of my mother, my girlfriend, my son," he told E! News of the controversial religion. "They never left my side, so why would I want buy into something that's not what I feel?"

He later added that he was "kind of" surprised that Leah would put out the series, but it certainly won't sway his beliefs.

He said, "As long as I get to still do it and my family gets to do it, I'm happy."

Since leaving the religion in July 2013, Leah has often been critical of Scientology. Asked recently if she expected to hear from either Travolta or star Scientologist Tom Cruise, she said, "They will not reach out to me. They are not allowed to reach out to me."

She later said, "John Travolta, by the way, is one of the nicest, sweetest people you're ever going to meet."

For the record, the church has denied essentially all of Leah's accusations, saying she is "desperate for attention with an acting career stuck in a nearly decade-long tailspin."

The viscous statement said Leah was "a spoiled entitled diva" while claiming she wanted to stay with the church.

"Her repeated ethical lapses and callous treatment of others led to an ecclesiastical review which resulted in her being expelled," the statement said. "She now regurgitates the tired myths the Church has repeatedly debunked, circulated by the same tiny clique of expelled former staffers bitter at having lost the positions they enjoyed before their malfeasance and unethical conduct were uncovered. Ms. Remini is now joined at the hip with this collection of deadbeats, admitted liars, self-admitted perjurers, wife beaters and worse."
