Yikes! Fans know that former Sex and the City stars Kim Cattrall and Sarah Jessica Parker have been involved in a long-standing feud dating back to pre-production for the first SATC film, but now the Kim vs. Sarah feud has taken a nasty turn. On Saturday, Feb. 10, Kim took to Instagram to share a scathing message directed at her former co-star, and she did not hold anything back.

"I don't need your love or support at this tragic time [Sarah Jessica Parker]," the 61-year-old wrote in a text post on Instagram. In the caption, she elaborated her thoughts in a lengthy caption.

"My mom asked me today,' When will that [Sarah Jessica Parker], that hypocrite, leave you alone?' Your continuous reaching out is a painful reminder of how cruel you really were then and now," Kim wrote. "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."

Kim's comment comes just days after she publicly thanked her fans, friends, and Sex and the City colleagues for the outpouring of support after her brother, Chris Cattrall, had been found dead after he went missing back in January. Kim's former co-stars left comments on Kim's Instagram post announcing her brother's death, and Sarah commented, "Dearest Kim, my love and condolences to you and yours and Godspeed to your beloved brother. Xx."

But Kim is not ready to accept Sarah's condolences amid their ongoing feud, which seemed to be reignited after rumors started to spread about the possibility of a third SATC film. Rumors claimed that the production was stalled because Kim was demanding a salary raise, but she revealed that it was because she just didn't want to put herself in what she called a "toxic" situation.

"Nobody ever picks up the phone and tries to contact you and say, ‘How [are] you doing?' That would have been the way to handle it,” she told Piers Morgan during an interview back in October. “This is, it feels like, a toxic relationship.”
