Kim Cattrall's response to her Sex and the City costar Sarah Jessica Parker was rather indifferent than her message to Cynthia Nixon. In an Instagram post, Cattrall accused Parker of leveraging the former's brother's death to advance her "nice girl" image.

"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," Cattrall captioned on a post. Cattrall pointed out that Parker is not friend or family and that the latter should respect her family's privacy.

In contrast, Cattrall gave an appreciative message to Nixon thanking for the effort to reach out. Reports have circulated that it appears that Nixon must have called Cattrall personally rather than posting on social media.

"Cynthia, hearing your voice meant so much to me. Thank you for reaching out. Love Kim #SexandtheCity," Cattrall wrote. The comment was posted days after Cattrall lambasted Parker on the social media site.

'Toxic' Relationship

In the same caption, Cattrall referenced to a New York Post, where she said she was disappointed as to how little the girls have spoken to each other after the show. She added that the sitcom's "Mean Girls," referring to their 'toxic' relationship ultimately caused its demise.

In October 2017, the girls' rift went public again when Cattrall told journalist Piers Morgan that she was "never friends" with Parker and they were plain "colleagues."

"I really think [Parker] could have been nicer," Cattrall said.

There have been rumors of a third film since December 2016, but Parker who was also the executive producer, quickly ruled out its possibility during the New York City Ballet Fall Gala last year. Meanwhile, Cattrall said that her answer had always been no to any possible movie collaboration in the future.

"For me, it's over. It's over with no regrets," she said.

In February, Parker said she was "just heartbroken" in response to Cattrall's comments.

An Unlikely Disappearance

Chris Cattrall, 55, was reported missing on Jan. 30. His sister, Kim, appealed to the public to help on the search efforts, saying that it is unlikely her brother to leave unadvised. Upon his disappearance, he left behind his house unlocked and seven beloved dogs.

On Feb. 4, Royal Canadian Mounted Police found Chris' body in the rural areas of Blackfalds, Alberta, Canada. Authorities ruled there was nothing suspicious about Chris' death. Details of the investigation are yet to be released.

Sex and the City was one of HBO's long-standing show which aired from 1998 to 2004.
