Kim Cattrall has had it with Sarah Jessica Parker. Officially.

Cattrall, whose missing brother was found dead last weekend in Canada, made it clear today on social media that condolences are not welcome from her former Sex and the City co-star.

“I don’t need your love or support at this tragic time @sarahjessicaparker,” Cattrall wrote on Instagram.

"My Mom asked me today 'When will that @sarahjessicaparker, that hypocrite, leave you alone?'" the 61-year-old actress continued. "Your continuous reaching out is a painful reminder of how cruel you really were then and now."

"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 linked to a New York Post article titled "Inside the mean-girls culture that destroyed 'Sex and the City.'"

In an earlier Instagram post, Cattrall had thanked her “#SexandtheCity colleagues” for their outpouring of support following the tragedy.

Parker had commented on Cattrall’s initial post announcing her brother's death, writing, “Dearest Kim, my love and condolences to you and yours and Godspeed to your beloved brother.” SATC co-star Cynthia Nixon also left a note in the comments.

Last year, after confirming that she would not participate in a third Sex and the City movie, Cattrall told Piers Morgan that she was not close with her co-stars. "We’ve never been friends," she said. "We’ve been colleagues and in some ways it’s a very healthy place to be.”

Parker later told Andy Cohen on Watch What Happens Live that she was "heartbroken" by the Cattrall's statements.

Let's hope Ryan Murphy is taking notes for an upcoming season of Feud.
