Kim Cattrall has vented her anger at former Sex and the City co-star Sarah Jessica Parker.
The two had reportedly been at odds since filming the show together, with the recent demise of any prospects for a third Sex and the City film bringing the animosity back to the surface.
"I don't need your love or support at this tragic time (Sarah Jessica Parker)," Cattrall posted on Instagram on Sunday.
In the caption, she called Parker a "hypocrite" and "cruel", adding: "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."
Cattrall was likely referring to the recent death of brother Chris, which Parker discussed during the Paley Centre for Media's An Evening With the Cast of Divorce in New York City Thursday.
"If somebody in your life, whether you're in touch with them or not, (is) suffering for any reason, it's involuntary that you want to convey condolences or sadness, or just let someone know you're thinking about them," she said, according to Entertainment Tonight.
Parker had also left a message of condolence on Cattrall's Instagram post, announcing her brother's passing, as had Cynthia Nixon, another SATC co-star.
On Instagram, Cattrall also linked to a New York Post article from October, entitled ‘Inside the Mean-Girls Culture That Destroyed Sex and the City’.
The article describes the finger-pointing at Cattrall that occurred, after it was announced that the third SATC film would not be made, as well as the friction between the Cattrall and Parker on-set.
The article claimed a clique that excluded Cattrall formed on the set of SATC, particularly after creator and producer Darren Star left and Parker's friend Michael Patrick King took over, which led to Cattrall's reluctance to participate in the first SATC film.
After its financial success, producers - including Parker - wanted to continue with asecond, but Cattrall remained hesitant, which led to rumours that her "diva" behaviour caused the film's holdup.
She eventually signed on, however, after receiving a higher salary.
