Kirstie Alley didn't hold back when she was asked about ex-Scientology pal Leah Remini. In an interview with Howard Stern, Alley slammed the "King of Queens" star, "I think that is the most repulsive thing that a person can do is attack another person's faith." She added, "I have blocked her on Twitter. Because she's a bigot!"

"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 bullis**t," she said. "However, 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 went, "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."

During the chat, Alley also opened up that she became attracted to Scientology when she drove by the Celebrity Center in L.A. and "saw all these Porsches and Mercedes parked outside." She said, "I was like, 'These people are rich!' " She additionally admitted she first read L. Ron Hubbard's book while snorting coke.

"This is either the world's biggest sham or the world's biggest discovery. So I decided I'm moving to California to find out," she thought after finishing the book. When her parents warned her against getting involved with a cult, she looked up the word in dictionary and found it to be "benign." "Cult didn't scare me," so she said.

In response to Alley's diss, Remini quoted Mark Twain's line on Twitter, "It is better to remain silent and be thought a fool than to open one's mouth and remove all doubt." She added, "Something I wish I had practiced! Lol."
