It all started last Wednesday when Alley wrote, "When faced w malicious gossip I take a moment to experience the loss of the person I thought was my friend... Then I say f--k em..:)"
She later added, "The sweetest poison is often served with a smile...beware syrup."
Rumors soon surfaced that Alley's remarks were aimed at Remini, despite the fact that Remini's announcement that she was qutting the controversial religion was made the day after Alley posted her scathing criticism.
"Lying news outlets. I do NOT care what religion ANYONE is or isn't. I respect religions & would fight for your freedom as well as mine," Alley tweeted on Monday in response to all the speculation.
She continued, "Thank U lying 'news' outlets for thinking I have ESP & write tweets 'BEFORE' events OCCUR. I accept that compliment. Ur 'sources' don't exist."
Alley then quipped, "I'll just be here learning my lines 4 the movie I haven't been offered yet. And buying lottery tickets for The Cal lottery I won in Jan 2014."
Last Thursday, the New York Post reported that Remini had decided to leave the Church of Scientology, citing a source's claim that the 43-year-old actress had been subjected to years of "interrogations" and "thought modification" after questioning the leadership of David Miscavige.
When asked for a comment, a rep for the Church of Scientology told E! News, "The Church respects the privacy of parishioners and has no comment about any individual Church member."
The Church later added that allegations of "interrogations" and "thought modification" are "absurd and pure nonsense."
