Cattrall took to Instagram on Saturday morning to call out Parker for being "cruel".
She continued: "Let me make this VERY clear". "Obviously 50 percent of marriages don't work and I think when you see other people on TV having troubles maybe you feel less alone and understood".
"You are not my friend", Cattrall wrote in a message directed at Parker, less than one week after her 55-year-old brother, Chris Cattrall, was found dead at his home in Canada. "So I'm writing to tell you one last time to stop exploiting our tragedy in order to restore your 'nice girl" persona", she wrote. She later drew close to the fourth star, Kristin Davis.
Even late past year, when news emerged that there would not be a third SATC movie, Sarah Jessica Parker made a public statement about her disappointment, despite the fact that Cattrall had made it very clear in 2016 that she'd never take part in a SATC movie again.
On Instagram, Cattrall also linked to a New York Post article from October entitled Inside the Mean-Girls Culture That Destroyed Sex and the City.
However, it seems the war is far from over, as Kim has branded Sarah a "hypocrite".
In the current season that debuted in January, Shannon's quirky character struggles to find her own identity while her husband enjoys retirement.
"The common ground that we had was the series and the series is over", Cattrall told Morgan. She also told Extra, "I can't begin to know how her family is managing such a loss". "It's sad. It was a professional experience, but it became personal, because it was years and years of our lives".
