Meow! Kirstie Alley has reignited her feud with former Scientologist Leah Remini in a big way, telling Howard Stern that Remini is a "repulsive" "bigot" who she's blocked on Twitter.

Remini left the Church of Scientology this summer, leaving fellow Scientologist Alley feeling "bitterly betrayed," Breaking Celebrity News has reported. Making matters worse, she has spoken publicly about her decision, saying she "could no longer be affiliated with" Scientology because of their dealings.

"I think that is the most repulsive thing that a person can do," Alley told Stern on Wednesday,"is attack another person's faith."

"No one cares that she's left Scientology," Stern responded. "Are you upset with her that she's being so f****g vocal and critical about it? Or you don't care?"

"First of all," Alley said, "I just want everyone to know that I have hundreds of friends who have come into Scientology and left Scientology … You're not shunned, you're not chased. All that stuff's bullish*t."

"However," she snapped, "when you are generalizing and when your goal is to malign and to say things about an entire group … when you decide to blanket statement that Scientology is evil, you are my enemy."

"The truth is I don't think I've seen Leah for like seven or eight years," she admitted, "not for any reason other than I'm acting and she's acting. ...

I didn't care if she was in or out, I honestly didn't."
