During her interview with The Daily Beast, Remini says she is positive Smith is a member of the church.
"I know Jada's in. I know Jada's in. She's been in Scientology a long time," Remini told The Daily Beast. "I never saw Will [Smith] there, but I saw Jada at the Celebrity Centre. They opened up a Scientology school, and have since closed it. But Jada, I had seen her at the Scientology Celebrity Centre all the time."
Remini also spoke about her tell-all memoir Troublemaker, in which she admits to seeing Smith at a party held at Tom Cruise's home.
The former King Of Queens star has dedicated herself to exposing the dark issues within the religion on her Emmy-winning documentary series, Leah Remini: Scientology and the Aftermath on A&E.
Smith has not commented on the rumors.
