Kirstie Alley is under heavy attack, being slammed by fans about her Scientology ties and also blasted by Leah Remini’s outspoken older sister Nicole, who says she wrote “Shame on you” on the star’s Facebook page, Breaking Celebrity News is reporting.

Leah’s defection from Scientology led Nicole to reveal unflattering details about the church, its leadership and celebrity members. And while Kirstie has avoided directly mentioning Leah, a former friend, she has sent out cryptic tweets that appear to address the situation.

One report claimed that Kirstie organized a gathering at the home of Leah’s former best friend to discuss how a group of Scientologist would “disconnect” from Leah. The report is unconfirmed and Kirstie,, again not addressing it directly, appears to be denying it through Twitter. (Scientology denies that it asks members to “disconnect” from people who leave the church.)

Asked about Kirstie’s alleged actions, Nicole told Twin Cities radio station MyTalk 107.1: "I even think about Kirstie Alley. I just wrote on her Facebook page, 'Shame on you.'"

She added: “So Kirstie jumped on the cuckoo train with (church head) David Miscavige. Because this is what's funny to me, "really, Kirstie? When was the last time you hung out with my sister?" I mean, I don't remember Kirstie ever being at my sister's house. We've been to Kirstie's. Maybe 10 years ago. Maybe they've seen each other at events. But when hurricane Sandy happened, Leah reached out the Kirstie, and said, "Hey, let's get some generators and see what we can do to help, let's do this." And Kirstie never even called Leah back. This is before everything happened.”

Nicole is not the only one who is going after Kirstie.
