Kim Cattrall is calling out her former “Sex and the City” co-star Sarah Jessica Parker over her message of sympathy following the tragic death of Cattrall’s brother.

Chris Cattrall was found dead at age 55 on the property of his Alberta home after being missing for several days, with his sister sharing the sad news of his passing via Twitter on Feb. 4.

Cattrall later reached out on Instagram to thank “my fans, friends and #SexandtheCity colleagues for the outpouring of support,” after co-stars Cynthia Nixon and Sarah Jessica Parker offered their condolences on social media.

On Thursday at a promotional event for her TV Show “Divorce”, Parker told Entertainment Tonight of Cattrall’s brother’s death: “If somebody in your life, whether you’re in touch with them or not, [is] suffering for any reason, it’s involuntary that you want to convey condolences or sadness or just let someone know you’re thinking about them.”

On Saturday morning Cattrall offered a very different take on Parker’s messages of condolence, taking to Instagram to let her former co-star know exactly what she thought.

“My mom asked me today, ‘When will that @sarahjessicaparker, that hypocrite leave you alone?'” wrote Cattrall, 61. “Your continuous reaching out is a painful reminder of how cruel you really were then and now.”

Cattrall continued: “Let me make this VERY clear. (If I haven’t already) You are not my family. You are not my friend. So I’m writing to tell you one last time to stop exploiting our tragedy in order to restore your ‘nice girl’ persona.”

Cattrall also attached a link to a New York Post article with the headline, “Inside the Mean Girls Culture that Destroyed ‘Sex and the City’.”

The article, published in October 2017, details how Cattrall was painted as the “villain” after plans for a third “Sex and the City” film fell apart, alleging issues over the disparity between Cattrall’s and Parker’s salaries, with a friend of Cattrall telling the Post that “Kim does not want to… do the film. She feels she has been treated horribly by Sarah Jessica Parker for six years.”

That same month, Cattrall gave an interview to Piers Morgan, stating that she doesn’t consider herself to be friends with any of her ‘SATC’ co-stars. “We’ve never been friends,” Cattrall said, according to The Daily Mail. “We‘ve been colleagues and in some ways, it’s a very healthy place to be because then you have a clear line between your professional life and relationship and your personal.” In another part of the interview, she admitted the lack of contact from her co-stars “feels like a toxic relationship.”

Parker, during an appearance on “Watch What Happens Live”, said that she was “heartbroken” by Cattrall’s statements, adding, “I found it very upsetting because that’s not the way I recall our experience.”

ET Canada has reached out to Parker’s rep for comment following Cattrall’s social media posts about her.

After giving that explosive interview to Morgan, the British TV host tweeted Cattrall his support, writing that he’s “100 per cent behind @KimCatrall on this. “Nothing worse than someone who’s treated you like dirt suddenly pretending to care about you to make themselves look good in the public’s eyes.”
