NEW YORK (CBSNewYork/AP) — Kim Cattrall has a message for Sarah Jessica Parker: Spare me your sympathy.

Cattrall lashed out at her former “Sex and the City” co-star after Parker expressed support over the death of Cattrall’s brother, Chris.

In an Instagram message posted Saturday, Cattrall wrote that Parker is not a friend and called her a hypocrite.

“Your continuous reaching out is a painful reminder of how cruel you really were then and now,” Cattrall wrote. “Let me make this VERY clear. (If I haven’t already) You are not my family. You are not my friend.”

Cattrall continued, claiming Parker used her family tragedy to restore her “‘nice girl’ persona.”

The two actresses reportedly have not gotten along for years. According to the New York Post, the pair’s rocky relationship recently resurfaced after Cattrall confirmed that a highly anticipated third “Sex and the City” film was no longer in the works.

Cattrall’s brother was found dead last week. He was 55.
