Kim's brother, Chris, was found dead last week after going missing from him home in Canada.
When Kim announced his death, she thanked her fans and SATC colleagues for the support they were lending her.
HOWEVER, she did a follow-up post that was a direct message to Sarah... and it's brutal.
"I don't need your love or support at this tragic time @sarahjessicaparker," the image read. But she added the caption, "My Mom asked me today 'When will that @sarahjessicaparker, that hypocrite, leave you alone?' 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.

Whoa.
The article that Kim links is from the New York Post in October, 2017. In it, the ongoing feud between Kim and Sarah is described, leading to how Kim left the franchise when the third film was announced.
Sarah has yet to respond.
