Cattrall's brother was found dead last week at the age of 55.
In years past, both women had made a point of denying any bad blood between them where the public was concerned, with Parker saying things like how she "adores" Cattrall and Cattrall reciprocating by calling her former small and silver screen partner "fantastic".

Now, the dispute with Parker is in the open, with Cattrall posting last Saturday: "I don't need your love or support at this tragic time".
She said, "It is with great sadness that myself and my family announce the unexpected passing of our son and brother, Chris Cattrall".
Parker has claimed she reached out to the 61-year-old after the news of her brother's death, and told Extra on Thursday (08Feb18) she "rang and texted" her TV co-star when she heard Chris had gone missing. Cattrall responded to that story by insisting that she never agreed to do the film, that Parker should've been "nicer" to her, and that she and her co-stars had "never been friends". "We all send her our love and condolences and grant her the privacy that she's asked for", she said.
