Sarah Jessica Parker sent her condolences to former “Sex and the City” co-star Kim Cattrall after she confirmed her brother, Chris Cattrall, had passed away.

Parker, 52, took to Instagram to share a heartfelt message after Cattrall announced the tragic news.

Cynthia Nixon, 51, who played Miranda Hobbes in the HBO series, also commented to send her love.

On Tuesday, Cattrall responded by tweeting her thanks to fans, friends and her “Sex and the City” co-stars.

The comments come after Cattrall, 61, confirmed that her brother Chris, 55, who had been missing since last Tuesday, had died.

On Saturday, the actress took to social media to seek help finding her brother, who lived in Lacombe, Alberta, and hadn’t been seen since Jan. 30. On Sunday, she tweeted of her brother’s “unexpected passing.”

RCMP Cpl. Laurel Scott told Global News that Chris Cattrall’s body was located somewhere on his property Sunday. It wasn’t specified whether the body was found inside or outside the home.

Scott added that police have no reason to believe there was anything suspicious related to the cause of death.

Cattrall initially took to social media to report her brother had gone missing, leaving his keys, cellphone, and wallet on a table in his home, while his front door was left unlocked and seven dogs unattended.

“This is not like Chris,” wrote Cattrall in the earlier post. “He would never leave his unlocked home without those items nor his 7 beloved dogs.”

“He’s a one of a kind brother,” she added. “Help us bring him home safe. Please spread the word.”
