with prominent celebrity scientologist, kirstie alley, lashing out at leah remini, calling her a bigot for attacking other people of faith. Alley says that is plain wrong. Reporter: Since leaving scientology over the summer, leah remini has been vocally critical of her former faith. Now, she is getting public blowback from kirstie alley, a proud scientology who appeared on "the howard stern show" on thursday. When you decide to blanket statement that scientology is evil, you are my enemy. Reporter: Alley, who credits scientology with getting her off of cocaine and vastly improving her life, seem to be upset like ones remini made on "the view," 2 1/2 weeks ago, after being eliminated on "dancing with the stars." You've been open about leaving the church of scientology. Had there been repercussions at all? Yes. Many repercussions. But the one I think people can relate to is shunning because i don't think everybody knows that that's what is required when you leave.

Alley, also says she has blocked remini on twitter. Yeah. She's a bigot. Reporter: We reached out to remini's publicist who had no comment. For "good morning america," dan harris, abc news, detroit.
