Leah Remini is calling out NBC Los Angeles after the local station aired an advertisement for the Church of Scientology. "Scientology has often bought 30-second and 1-minute TV ads (mostly on local television)," Remini, 55, wrote via X on Monday, December 29. "It is something I strongly object to, but allowing Scientology to buy a full 30-minute block of airtime is unacceptable." According to the former King of Queens actress, "Someone who knows nothing about Scientology and happened to watch this program would not realize that it was a paid advertisement and might reasonably assume it was programming produced or endorsed by NBC, which could lead them into Scientology." Us Weekly has reached out to NBC Los Angeles and the Church of Scientology for comment. Celebrity Scientologists and Stars Who Have Left the Church July marked 12 years since Remini famously left the Church of Scientology. Since renouncing the controversial organization, the former cohost of The Talk has written about her experience in a memoir, Troublemaker: Surviving Hollywood and Scientology. She also starred in the Emmy-winning A&E docuseries, Leah Remini: Scientology and the Aftermath. In response, the Church of Scientology issued a statement regarding Remini on its website, claiming the actress was "expelled" from the organization because of her "repeated ethical lapses." The organization also accused the actress of harassing her former church. Before 2025 comes to an end, Remini asked her supporters to contact NBC Los Angeles to "let them know what a serious mistake this was and urge them to never again allow Scientology to purchase a block of airtime like this." Leah Remini Spills on Tom Cruise, John Travolta and More Scientologists "For a major network to present this material in this way is deeply alarming," she claimed. "I understand that Scientology has been purchasing increasing amounts of advertising time across the country, but this crosses a line." In a June cover story with Us, Remini opened up about her life after leaving the Church of Scientology more than a decade ago. "I've learned just how strong I really was. I was willing to stand up for what I believed in," she told Us, adding that she doesn't regret using her voice to raise awareness about the church's alleged controversies. Leah Remini's Battle With Scientology: What She's Said About the Religion "Listen, I'm still an a**hole. [Laughs.] I have a temper. I'm trying to be better, but I'm never going to be a perfect person, and I'm not trying to be," she added. "The other lesson I've learned is being OK [with] being uncomfortable. That's where I'm finding growth. Even [in Scientology], there was comfort. I'm supposed to say this and feel that. Right now, it's like, 'You're on your own, kid.'" When asked about her religious beliefs today, Remini - who shares daughter Sofia, 21, with estranged husband Angelo Pagán and is currently working towards a bachelor's degree in social sciences from NYU - explained that she believes in God. "I was baptized [as a] Catholic when I was a child. I don't force religious beliefs on myself or my daughter, but I believe in God and in faith," she explained. "As Mike [Rinder] said, 'If you want to know the difference between a real religion and Scientology, look at what they do when you leave.'"
